The selling price of an article is 20% less than its marked price and the marked
price is 30% above the cost price. Find the profit percent.
Answer:
sp=mp-20%ofmp=0.8mp
mp=cp+30%ofcp=1.3cp
mp=1.3cp
cp=mp/1.3
profit %=?
Step-by-step explanation:
profit=sp-cp=0.8mp-mp/1.3=(1.04mp-mp)/1.3=0.04mp/1.3=0.0307mpProfit %=profit/cp×100%=0.0307mp/mp/1.3×100%=0.0307×1.3×100%=3.991%=4%The profit percentage is 4% .
What is profit percentage?Profit percentage (%) is the amount of profit expressed in terms of percentage. This profit is based on the cost price .
Formula for profit percentage is:
(Profit/Cost Price) × 100
where,
Profit = Selling price - Cost price
According to the question
Let Cost price of the article = 100x
marked price is 30% above the cost price
i.e marked price = [tex]\frac{130}{100} * 100x[/tex]
= 130 x
selling price of an article is 20% less than its marked price
i.e Selling price of the article = [tex]130x * \frac{100-20}{100}[/tex]
= [tex]130x * \frac{80}{100}[/tex]
= 104 x
Now ,
Profit = Selling price - Cost Price
Profit = 104x -100x
Profit = 4x
Profit percentage = [tex]\frac{Profit}{Cost PRice} *100[/tex]
substituting the values in formula
Profit percentage = [tex]\frac{4x}{100x} *100[/tex]
Profit percentage = 4%
Hence, the profit percentage is 4% .

At Paulson Middle School, 75% of the sixth grade class is making a B or higher. If there are 21 students
making a B or higher, then how many students are in the class?
Answer:
28 students
Step-by-step explanation:
x = Number of students
21 students = 75 percent of x = 3/4 x
3/4 x = 21
x = 21 * (4/3) = 7*4 = 28

Any one know the y intercept?
y=2x+-3
Answer: -3
Step-by-step explanation:
the number at the end of the equation is the y-intercept. it's called "slope-intercept" form because the 2x that is at the beginning represents the slope, and the -3 at the end represents the y-intercept.
hope this helps!
Answer:
x= 3/2
Solution:
y=2x-3
Substitute y=0
0=2x-3
Move the variable to the left
-2x=-3
Divide by both sides
x= 3/2

Answer:
-25 and -4
Step-by-step explanation:
to solve this, you need to use the sum product pattern. this means you're going to take the x factor, 29x and separate it into it's squares.
(x^2+25x)+(4x+100)
then you take out the common factor in each separated equation
x(x+25)+4(x+25)
you see that the items in the parentheses are the same, this means that this is one of the equations you will use when factoring. the rest of the equation that is left out (the common factors) is the other equation
(x+25)(x+4)
to get the zeroes, you set each equation equal to zero and solve
x+25=0 x+4=0
x= -25 x= -4
5) The school that Lexy goes to is selling tickets to the annual talent show. On the first day
of ticket sales the school sold 14 adult tickets and 11 student tickets for a total of $128. The
school took in $88 on the second day by selling 14 adult tickets and 1 student ticket. What
is the price of each adult ticket and student ticket?
$6.00 for adult tickets and $4,00 for student tickets
how do you work it out
Answer:
Adult ticket is $6
Student ticket is $4, as you said.
Step-by-step explanation:
We'll call adult tickets x and student tix y.
14x + 11y = 128
14x + y = 88
First, solve the second equation for y in terms of x:
y = 88- 14x
Then substitute that for y into the first equation:
14x + 11(88-14x) = 128
14x + 968 - 154x = 128
-140x = -840
x = 6 The adult ticket is $6, like you said.
Now take that and solve for y:
y = 88 - 14(6)
y = 88 - 84
y = 4 The student ticket is $4, as you said.
Hope this helps. Feel free to ask questions so you can understand.

AAAH HELP! Assume that r varies directly as p. What is the constant of proportionality if r = 3 when p = 15. k = 1\5 k = 5 k = 3 k = 45
Answer:
k = [tex]\frac{1}{5}[/tex]
Step-by-step explanation:
Given that r varies directly as p then the equation relating them is
r = kp ← k is the constant of variation
To find k use the condition r = 3 when p = 15, then
3 = 15k ( divide both sides by 15 )
[tex]\frac{3}{15}[/tex] = k , that is
k = [tex]\frac{1}{5}[/tex]

Find the part. What is 110% of 14.9?
Answer:
16.39
Step-by-step explanation:
Solution 1: You can turn the words into Algebra so What (x) is(=) 1.10 of (multiply)14.9, So x = 1.10 (14.9). x= 16.39
When you see the word what, place an 'x', is means '=', 110% = 1.10
Solution 2: Notice how 100 percent is already 14.9 so 110% should be greater than 14.9, so we're missing another 10%, and 10% of 14.9 is 1.49 just by moving the decimal over. So you would need 14.9 + 1.49 more, so a total of 16.39.

what is the slope help pls?
Answer:
y=7x-6
Step-by-step explanation:
You would first pick two coordinates in this case would be ( 0, -6), (1,1). You would find your slope by using the formula y2-y1/x2-x1. Which would give you a slope of 7/1 which is equal to 7. Then you would use point slope formula which is y-y1=m(x-x1). would would plug in the numbers and it would say
y-(-6)=7(x-0). Then you would simplify the y-(-6) which would be y+6 then you would distribute the 7. Your whole equation would look like y+6=7x+0. Then you would use inverse operations and subtract -6 from the left side of the equals and subtract it from 0 giving you -6. Therefore your whole equation would be y=7x-6. Hoped this helped.

how can you get 2 1/2÷5/8
Answer: 4
Step-by-step explanation:
Change the 2.5 to an improper fraction, then multiply by the reciprocal of 5/8.
[tex]2\frac{1}{2} /\frac{5}{8} =\frac{5}{2}*\frac{8}{5}=\frac{40}{10} =4[/tex]
Conversion a mixed number 2 1/

) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step , cancel by a common factor of 10 gives 4/

2. y = 2
Just copy these steps on paper, then submit.
Writing it yourself will help you, trust me :)
1. 2(x + 5) = 3x + 1
2(x + 5) = 3x + 1
Distribute the 2
2x + 10 = 3x + 1
-1 -1
2x + 9 = 3x
-2x -2x
9 = x
2. 3y - 4 = 6 - 2y
3y - 4 = 6 - 2y
+4 +4
3y = 10 - 2y
+2y +2y
5y = 10
Divide both sides by 5
y = 10/5
