The friend will get 12 issues for $15.

What is a Ratio?

A ratio indicates the number of times one number contains another.

Given that, the friend pays $1.50 per issue:

$1.5 = 1 issues

$1 = 1/1.5 issues

$15 = (1/1.5) × 15 issues

$15 = 10

Since the friend gets the first two issues free, he will get 10 + 2 =12 issues.
