Problema Solution
University Theater sold 445 tickets for a play. Tickets cost $20 per adult and $10 per senior
citizen. If total receipts were $5790, how many senior citizen tickets were sold?
Answer provided by our tutors
x + y = 445
20x + 10y = 5790
y = 445 - x
20x + 10(445 - x) = 5790
10x = 5790 - 4450
10x = 1340
x = 134
445 - 134 = 311
134 adult tickets and 311 senior tickets
