Please show the equation you used to solve. 1. Tickets for the drama club's performance last weekend cost $2.50 for adults and $2.00 for students. Four hundred twenty adults attended the performance, and 273 students attended. What was the total ammount of money collected from tickets for the performance last weekend? 2. Gregory ordered the following items from the Huntington Gardens catalog: a watering can for $15.80, a trowel for $4.49, and 6 packages of seeds for $.75 each. He must add $2.50 for shipping charges. He has 2 coupons, each allowing him to deduct $2.00 from his order. How much will Gregory pay for the order? 3. Sarah Holness had her car tuned up for $60 and she purchased 4 new tires for $37 each. She gave the cashier 11 twenty-dollar bills. How much change did Sarah receive? Thanks!
