Cindy spent $65.25 on ingredients for blueberry pies and $62.84 on ingredients for cherry pies. Each slice of ple sells for $3.50.
Part A
Write an expression to represent Cindy's profit if she sells b slices of blueberry pie and C slices of cherry ple.
Part B
Cindy sells 24 slices of blueberry ple and 15 slices of cherry ple. The ne
xt day, she sold 26 slices of blueberry ple and 17 slices of cherry pie. What was her total profit?
The expression that represents Cindy's profit is $3.5b - $128.09.
Cindy's total profit is $30.82.
What is profit?Profit is total revenue less total cost. Total revenue is the selling price per unit multiplied by the total units sold.
Profit = total revenue - total cost
($3.50b) - ($65.25 + $62.84)
$3.5b - $128.09
What is Cindy's total profit?Profit for the first day = $3.5(24 + 15) - $128.09
= ($3.5 x 39) - $128.09
= $136.50 - $128.09
=$8.41
Profit for the next day = $3.5(26 + 17) - $128.09
= ($3.5 x 43) - $128.09
= $150.50 - $128.09
= $22.41

13. Suppose a real estate agent receives 5%
commission on the fi rst $200 000 of a
house’s selling price, and 6% on the
remaining amount.
a) What does commission mean?
b) If a house sells for $345 000, how
much commission does the real estate
agent make on the sale of the house?
Answer:
Commision may be defined as a percentage cut which an employee, broker, vendor, retailer or other persons within a sale chain receive from an employer or production firm for selling a good or offering a successful service based on agreed terms by both parties. ;
$18700
Step-by-step explanation:
Given :
Commision pattern :
5% on first $200,000
6% on remaining amount
Amount of commission on $345000
0.05 * 200000 = 10,000
0.06 * (345000 - 200000) = 8700
Total commission :
10,000 + 8700 = 18,700
From the equation y−3=−2(x+1), identify the slope and a point on the line.
Answer:
slope = - 2, point on line = (- 1, 3 )
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 3 = - 2(x + 1) ← is in point- slope form
with slope m = - 2 and (a, b ) = (- 1, 3 )
The slope of equation y−3=−2(x+1) is -2.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
y−3=−2(x+1)
Using Slope- Intercept form
y= mx + b
So, the slope for the equation is -2.
Hence, the slope is -2.

What is the equation of the line that passes through the point (5, -2) and has a slope of 6/5
Answer: y = (6/5)x-8
Slope = 6/5 = 1.2
Y intercept = -8
==================================================
Work Shown:
m = 6/5 = 1.2 is the given slope
(x,y) = (5,-2) is the point the line goes through
y = mx+b .... slope intercept form
y = 1.2x + b .... plug in the given slope
-2 = 1.2*5 + b ... plug in the coordinates of the given point
-2 = 6 + b
-2-6 = 6+b-6 .... subtracting 6 from both sides
-8 = b
b = -8
The equation y = mx+b turns into y = 1.2x-8
This is equivalent to y = (6/5)x-8
Put the following lengths in ascending order, 900cm, 8.9m, 895cm, 9.1m, 12000mm, 0.0092km.
Answer: 8.9 m, 895 cm, 900 cm, 9.1 m, 0.0092 km, 12000 mm
===========================================================
Explanation:
To be able to compare these various measurements, all of them must be the same unit. Let's convert each measurement to meters. If the measurement is already in meters, then we'll move onto the next measurement.
Here are some useful conversion factors
1 m = 100 cm1 m = 1000 mm1 km = 1000 mWith those conversion factors in mind, we get the following conversions:
900 cm = (900 cm)*(1 m/100 cm) = (900/100) m = 9 m8.9 m = already in meters, moving on895 cm = 8.95 meters; divide by 100 to convert from cm to meters as shown above9.1 m = already in meters, moving on12000 mm = (12000 mm)*(1 m/1000 mm) = (12000/1000) m = 12 m0.0092 km = (0.0092 km)*(1000 m/1 km) = (0.0092*1000) m = 9.2 mHere is the summary of the conversions:
900 cm = 9 m8.9 m = 8.9 m895 cm = 8.95 m9.1 m = 9.1 m12000 mm = 12 m0.0092 km = 9.2 mThe original list of
{900cm, 8.9m, 895cm, 9.1m, 12000mm, 0.0092km}
becomes this equivalent list
{9 m, 8.9 m, 8.95 m, 9.1 m, 12 m, 9.2 m}
in that exact order.
After converting everything to meters, we can then sort the values from smallest to largest. Doing so gets us this sorted list of
{8.9 m, 8.95 m, 9 m, 9.1 m, 9.2 m, 12 m}
Then you convert back each measurement to its original form
{8.9 m, 895 cm, 900 cm, 9.1 m, 0.0092 km, 12000 mm}
which is the final answer.

The statement that best explains the relationship between lines FG and HJ is "They are not perpendicular because their slopes are not negative reciprocals."
What is a slope?The slope or gradient of a line in mathematics is a numerical representation of the steepness and direction of the line.
If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
To find the slope of a line passing through two given points, we use the formula:
slope = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are the coordinates of the two points.
For line FG, the two points are F(-4, 1) and G(0, -2):
slope of FG = (-2 - 1) / (0 - (-4)) = (-2 - 1) / 4 = -3/4
For line HJ, the two points are H(-4, -2) and J(0, 4):
slope of HJ = (4 - (-2)) / (0 - (-4)) = 6/4 = 3/2
The slopes of lines FG and HJ are not equal. However, we can see that they are not negative reciprocals of each other:
slope of FG = -3/4
slope of HJ = 3/2
Therefore, lines FG and HJ are not perpendicular because their slopes are not negative reciprocals of each other.

Megan Dunstall wants to know how many months it would take for $15,000 to earn $618.75 at 51/2% of simple interest?
Answer: 9 months.
Step-by-step explanation:
Simple interest = Principal x rate(in decimal) x Time(in years)
Given: Principal = $15,000 , rate = [tex]5\dfrac12\%=\dfrac{11}{2}\%= 5.5\%= 0.055[/tex]
Interest = $618.75
let t= time
Then,
[tex]618.75=15000\times 0.055\times t\\\\\Rightarrow\ t=\dfrac{618.75}{15000\times0.055}\\\\\Rightarrow\ t= 0.75\ or\ t=\dfrac34\ year[/tex]
1 year =12 months
[tex]\dfrac34\ year=\dfrac34\times12 = 9\ months[/tex]

How many bateria cells will there be when Jill looks at her sample on Day 4?
Answer:
8100
Step-by-step explanation:
We first see that in the first day it tripled from 100 to 300 this is the pattern that is seen throughout this whole experemint, we can see that the cells triple again on the second day to get 900 cells from this. It is likely to say that they will triple again on the third day to get 2100 and again on the fourth to get 8100
6(x-4)-x=6x+4 one solution, no solution or infinite solution
Answer:
no solution
Step-by-step explanation:
Given
6(x - 4) = 6x + 4 ← distribute left side
6x - 24 = 6x + 4 ( add 24 to both sides )
6x = 6x + 28 ( subtract 6x from both sides )
0 = 28 ← not possible
This indicates the equation has no solution
I need help graphing -8x-y=8
Answer:
y = -8x - 8
Step-by-step explanation:
Add -8x on both sides to get -y = 8x + 8 and flip the y sign on the left to get your slope function which is y = - 8x - 8.
To graph the function, you would need to put (0, -8) as your y-intercept, and each unit will go down 8 units when you add 1.
Answer:
y=8x+8
Step-by-step explanation:
Just rewrite the problem so it's in y=mx+b format then it's easy to graph
Remember the y intercept is 8 because when x=0 y=8 and the slope is 8 so go up 8 and right 1
