Ticket for a show where priced at $12 for adults and $7 for children the receipts for the show were $1,740 with 170 people in attendance how many adult tickets and how many children tickets were sold

Answer 1

C + A = 170

7C +12A = 1740

7C +7A = 7(170) = 1190

subtract to eliminate one variable

5A = 1740-1190 = 550

A = 550/5 = 110 adults

C = 170-110 = 60 children

7(60) + 12(110) = 420 + 1320 = 1740
