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:

[tex]\frac{7}{10}  = \frac{x}{4000}[/tex]

Cross multiply:

[tex]7 * 4,000 = 10*x[/tex]

[tex]28,000=10x[/tex]

Solve for x:

[tex]\frac{10x}{10} =\frac{28,000}{10}[/tex]

x = 2,800
