Question

A company sold 3,000 computers in one month, but 12 were returned. If 3,500 were sold the next month, the company would expect 14 to be returned.

What is a valid proportion to represent the problem?​

Answer 1

the last one is correct

Explanation:

because 3000/12 = 250 and 3500/14 = 250 so they are porportional.
