Answer
$$$32$$
Work Step by Step
$$y=x-15$$X is what we're trying to find. Y means the discounted price that the customer bought the shirt, which was 17 dollars. Plug in 17 for y: 17= x-15. To isolate the x by itself, we must add 15 to both sides: $$17+15=x-15+15$$. $$x=$32$$. This means the original price of the shirt was $32.
