Quinn spends $16.49 for 3 magazines and 4 sheets of stickers. The magazines cost $3.99 each and the sales tax was $1.02. Quinn also used a coupon for $1.50 off her purchase. If each sheet of stickers had the same cost, how much did each sheet of stickers cost?

I believe each sheet equals 1.76. Because if you add 1.50 and 1.02, you get 2.52. Then add 2.52 and 16.49, you'll get 19.01. After that you'll do 3.99 times 3 and get 11.97, subtract 19.01 from 11.97 to get 7.04. Finally do 7.04 divided by 4 to get 1.76.
cost of sticker ---- x 
3(3.99) + 4x + 1.02 - 1.50 = 16.49 
11.97 + 4x - .48 = 16.49 
4x = 16.49 - 11.97 + .48 
4x = 5.00 
x = 1.25
