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

Answer:

2,800 CUV cars were sold

Step-by-step explanation:

7 out of 10 are CUV

Total sold are 4,000

Set them equal to each other:

$\frac{7}{10} = \frac{x}{4000}$

Cross multiply:

$7 * 4,000 = 10*x$

$28,000=10x$

Solve for x:

$\frac{10x}{10} =\frac{28,000}{10}$

x = 2,800
