# In Exercises 17 to 22, use proportions to solve each problem.The secretarial pool (15 secretaries in all) on one floor of a corporate complex has access to four copy machines. If there are 23 secretaries on a different floor, approximately what number of copy machines should be available? (Assume a proportionality.)

To determine

To find:

The number of copy machines required for 23 secretaries.

Explanation

Approach:

According to Means-Extremes Property, in a proportion, the product of the means equals the product of the extremes.

Calculation:

Let us suppose x number of copy machines required for 23 secretaries.

It is given that 15 secretaries need 4 copy machines.

By form,

Numberâ€‰ofâ€‰secretariesNumberâ€‰ofâ€‰copyÂ machines=Numberâ€‰ofâ€‰secretariesNumberâ€‰ofâ€‰copyÂ machines
