3. ALGEBRA Nancy Boone's new automobile had an MSRP of
$27,853.00. The dealer prep charge was $278.50 and the title ſee
was $25.00. Options totaled $2,375,50. Find the sales tax rate,
to nearest hundredth percent iſ the total cost was $32 591.22
and the sales tax applied to everything but the title fee.
Answer:
The tax rate is approximately 6.75%
Step-by-step explanation:
In the question it is required to find the amount added to the total cost as tax
The given parameters are;
The Manufacturer's Suggested Retail Price, MSRP, of the automobile, MSRP = $27,853.00
The dealer prep charge, PPC = $278.50
The title fee, T = $25.00
The cost of the options added (leather, fridge, etc.), Op = $2,375.50
The total cost, C = $32,591.22
Let 'x' represent the the tax rate,
Therefore, we have;
32,591.22 = x × (27,853 + 278 + 2,375.5) + 27,853 + 278 + 2,375.5 + 25
32,591.22 = 30,506.5·x + 30,531.5
32,591.22 - 30,531.5 = 30,506.5·x
∴ 2,059.72 = 30,506.5·x
x = 2,059.72/30,506.5 = 0.06751741432 ≈ 0.0675
The tax rate, x ≈ 0.0675 = 6.75%

How much should a retailer mark up his goods so that when he has a 50% off sale, the resulting prices will reflect prices will still reflect a 75% markup, (on his cost)
Answer:
250%
Step-by-step explanation:
Let initial Markup % = x
Sales price = 100% + x = (1 + x)%
50% off sale = (1+x)% - (1+x)% /2
Final price after 50% off sale = 1 + 0.75 = 1.75
Hence,
50% off sale = 75% price markup
0.5(1 + x) = 1.75
0.5 + 0.5x = 1.75
0.5x = 1.75 - 0.5
x = 1.25 / 0.5
x = 2.5
Hence, Markup on initial price should be 1.25 = (2.5 * 100%) = 250%

Interest earned: $84
Principal: 600
Interest rate: 7%
Time: ?
Answer:
2 years
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 7%/100 = 0.07 per year,
then, solving our equation
t = 84 / ( 600 × 0.07 ) = 2
t = 2 years
The time required to
accumulate simple interest of $ 84.00
from a principal of $ 600.00
at an interest rate of 7% per year
is 2 years.

Rewrite each expression in factored form using the greatest common factor. 11. 16x+48 12. 28x+ 32y 13. 11w+hw pls help!!!
Answer:
16(x + 3)
4(7x + 8y)
w(11 + h)
Step-by-step explanation:
16x + 48
The greatest common factor of 16 and 48 = 16
Hence, expressing 16x + 48 in factored form:
16x + 48 = 16(x + 3)
28x + 32y
Greatest common factor of 28 and 32 = 4
Hence,
28x + 32y = 4(7x + 8y)
11w + hw
11w + hw = w(11 + h)

A ladder is leaning against a wall. If the base of the ladder is 8ft from the wall and the ladder is 16ft long, how high up does it sit on the wall? Leave your answer in simplest radical form and do not include units.
Answer:
height = 13.86, or 8√3
Step-by-step explanation:
using the Pythagorean theorem:
h² = 16² - 8²
h² = 256 - 64
h² = 192
h = 13.86 ft or 8√3
To express % as a decimal, move the decimal point ▼ two three one places to the ▼ left right and ▼ leave the number as it is. remove the dollar sign. divide by 100. remove the percent sign.
Question
To express 7.5 % as a decimal, _______, ___________ and remove the percent sign.
▼ move the decimal point [two] [three] [one] places to the [left] [right]
▼ leave the number as it is.
▼ remove the dollar sign.
▼ divide by 100.
Answer:
▼ move the decimal point [two] places to the [left]
▼ divide by 100.
Step-by-step explanation:
Given
[tex]Number = 7.5\%[/tex]
Required
Express as decimal [Select all correct options]
From the list of given options, the correct options are:
▼ move the decimal point [two] places to the [left]
▼ divide by 100.
To prove that the options are correct:
(1)
▼ move the decimal point [two] places to the [left]
7.5% becomes 0.075%
▼ Remove the percent sign
0.075% becomes 0.075
So:
[tex]7.5\% = 0.075[/tex]
(2)
Divide by 100
7.5% when divided by 100 is: 0.075%
Remove the % sign, we have: 0.075

It 16x = (141)²-(109)², then
the value of x is.
(a). 150
(b). 500
(c). 600
(d). 32
Answer:
b) 500
16x = (141)^2 - (109)^2
or, 16x = 19881 - 11881
or, x = 8000/16=500
Ryan has scores 32, 26, and 23 points in his four basketball games so far. How many points does he need to score in his next game so that his average (mean) is 26 points per game?
Answer:
23
Step-by-step explanation:
Ryan needs to score a 23 this game because if you add all the numbers together (32 + 26 + 23 + 23) then divide them
(32 + 26 + 23 + 23)/4
You will get 23.
Answer:
23 points
Step-by-step explanation:
Let's first start out by first finding the current mean. We can find this by:
[tex]\frac{32+26+23}{4}=27.[/tex]
So we know that his current average is 27 points per game, and we need the average to be 26. So, to find out the total number of points he scores from his 1st, 2nd, 3rd, and 4th game, we will do:
[tex]26\cdot4=104[/tex]
So if he needs 104 points in total to have an average of 26. So, we would subtract his total number of points from his 1st, 2nd, and 3rd game, from 104. If we do this, we would get:
[tex]104-(32+26+23)=104-81=23[/tex]
So he would need to score 23 points next game to have an average of 26 points.
What the slope? Can someone help me
Answer:The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

Find f(-) if f(n) = 5n + 6.
Answer:
f(-1) = 1
Step-by-step explanation:
Are you missing a number after the negative in f(-)?
If so, let me solve for f(-1) so substitute in the n with a -1 so f(-1) = 5(-1) + 6
so f(-1) = -5 + 6 so f(-1) = 1
