15t + 9.99 <= 500 -- subtract 9.99 from both sides
15t <= 500 - 9.99
15t <= 490.01 -- divide both sides by 15
t <= 490.01/15
t <= 32.66....you have to round it down to 32 because there can't be a .66 of a shirt.

check..
15(32) + 9.99 <= 500
480 + 9.99 <= 500
489.99 <= 500 (correct)

Ethan can order 32 or less t-shirts
