One evening 1500 concert tickets were sold. Tickets cost $20 for pavillion seats and $15 for lawn seats. Total receipts were $27,500. How many tickets of each type were sold?

500 lawn seats were sold and 1,000 pavillion seats were sold

Step-by-step explanation:

15 (cost of lawn seat) x 500 (amount sold) = 7500

20 (cost of pavillion seat) x 1,000 (amount sold) = 20,000

7,500 + 20,000 = 27, 500 (total receipts)
