(11)* A local movie theater charges $6 for each adult ticket and $3.50 for each child ticket. If the theater sold a total of 65 adult and child tickets for a total of $340, how many adult tickets were sold?

(12)* Tickets to a school play cost $5.00 for general admission and $3.50 with a student ID. On opening night, 400 tickets were sold for a total of $1580. How many general-admission tickets were sold?

(13)* Donna and Peggy went shopping and spent $84 altogether. Donna spent $15 less than twice as much as Peggy. How much did Donna spend?

(14)* Altogether Rob spent $52 for 2 shirts, including tax. The difference between the costs of the shirts was $18. What was the cost of the more expensive shirt?

(15)* Matilda paid a total of $8.10 for a belt, including tax. If the tax rate was 8%, what was the selling price of the belt?
