Question

At a local bank, a teller noticed that for every 17 checks that customers deposit with the bank, 5 take fewer than three days to process completely. Last week, 150 checks took fewer than three days to process completely. What is a reasonable estimate of the total number of checks that customers deposited with the bank last week?

Answer 1

5/17=x/150
x=(150x5)/17
x=about 44
