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?
Well for every 250 computers sold, 1 was returned. So if you multiply 12x250 you'd get 3,000. So 14x250 is 3,500. Or you could do 3,000 divided by 12 and you'd get 250. Same thing if you do 3,500 divided by 14.
