approximately what number of copy machines should be available? (Assume a proportionality. Round your answer to the nearest integer.)

Question

Use proportions to solve the following problem.

The secretarial pool (17 secretaries in all) on one floor of a corporate complex has access to four copy machines. If there are 25 secretaries on a different floor, approximately what number of copy machines should be available? (Assume a proportionality. Round your answer to the nearest integer.)

Answer 1

4/17=x/25

Cross-multiply and get

17x=4*25

Divide both sides by 17

x=100/17≈6

Answer 2

17 : 4 :: 25 : x

(4)(25) = 17x

Can you solve for x and answer? Remember you cannot have a fraction of a machine.
