At the city museum, child admission is 6.10$ and adult admission is 9.20$. Monday, four times as many adult tickets as child tickets were sold, = 1244.10$. How many child tickets were sold that day?

Answer 1

6.1C + 9.2A =1244.1 A=4C

6.1C + 9.2(4C) = 1244.1

6.1C + 36.8C = 1244.1

42.9C = 1244.1

C = 1244.1/42.9 = 29 child tickets

A = 4(29) = 116 adult tickets
