A car dealership pays 8358 for a car they mark up the price by 17.4% to get the retail price. What is the retail price of the ca

Ede4ka [16]

Answer:

<u>The retail price of the car is US$ 10,024 Rounding to the next whole</u>

Step-by-step explanation:

1. Let's check the information given to us to answer the question correctly:

Mark up the purchase price = 17.4%

Price of purchase of the car = $ 8,538

2. What is the retail price of the car at this dealership?

For calculating the retail price of the car, we will use the Rule of Three Simple, this way:

x = retail price of the car

x * 1 = 8,538 * 1.174

x = 10,023.61

<u>The retail price of the car is US$ 10,024 Rounding to the next whole</u>

(3.2x10^3) + (5.78 x 10^5) ?

meriva

Simple....

you have: $(3.2* 10^{3} )+(5.78* 10^{5} )$

Simplify....

$(3.2* 10^{3} )=3200$

and

$(5.78* 10^{5} )=578,000$

3,200+578,000=581,200

=581,200

Thus, your answer.

The area of a square floor on a scale drawing is 64 square centimeters, and the scale drawing is 1 centimeter:3 ft. What is the

Oxana [17]

Answer:

Part a) The area of the actual floor is $576\ ft^{2}$

Part b) The ratio of the area in the drawing to the actual area is $\frac{1}{9}\frac{cm^{2}}{ft^{2}}$

Step-by-step explanation:

we know that

The scale drawing is $\frac{1}{3}\frac{cm}{ft}$

step 1

Find the dimensions of the square on a scale drawing

The area of a square is equal to

$A=b^{2}$

where

b is the length side of the square

$A=64\ cm^{2}$

$64=b^{2}$

$b=8\ cm$

step 2

Find the dimensions of the actual floor

Divide the length of the floor on the drawing by the scale drawing

$8/(1/3)=24\ ft$

step 3

Find the area of the actual floor

The area of a square is equal to

$A=b^{2}$

substitute

$A=24^{2}=576\ ft^{2}$

step 4

Find the ratio of the area in the drawing to the actual area

$\frac{64}{576}\frac{cm^{2}}{ft^{2}}$

Simplify

Divide by 64 both numerator and denominator

$\frac{1}{9}\frac{cm^{2}}{ft^{2}}$
