at the movie theater child admission is 5.50 and adult admission is 9.10. on tuesday 145 tickets were sold for a total of 1132.30. how many tickets were sold that day

Answer 1

145 total, 93 adult tickets, 52 child tickets

C+A = 145

5.5C + 9.1A = 1132.3

5.5C + 5.5A = 797.5

subtract to get

3.6A = 334.8

A = 334.8/3.6 = 93

C=145-93 = 52
