A store had a sale on T-shirts. For every two T-shirts purchased at the regular price, a third T-shirt was bought for $1.00. Twelve T-shirts were bought for $120.00. What was the regular price for one T-shirt?

Regular price=P
8P + 4*$1 =$120
8P = $116
P = $116 /8
P=$14.50 - regular price of one shirt.
