Question

In 2015, nearly seven out of every ten autos sold in a country was a crossover utility vehicle (CUV). If an auto dealership sold 4000 vehicles in total that year, how many of these sales would be expected to involve a CUV

Answer 1

2,800 CUV cars were sold

Explanation:

7 out of 10 are CUV

Total sold are 4,000

Set them equal to each other:

`(7)/(10)  = (x)/(4000)`

Cross multiply:

`7 * 4,000 = 10*x`

`28,000=10x`

Solve for x:

`(10x)/(10) =(28,000)/(10)`

x = 2,800
