At the city museum, child admission is $5.60 and adult admission is $9.60. On Thursday, 153 tickets were sold for a total sales of $1088.80. How many child tickets were sold that day?

95 child tickets

Step-by-step explanation:

a+c = 153 c = (153-a) you need to plug this for c

9.6a + 5.6 (153-a) = 1088.8

9.6a + 856.8 - 5.6a = 1088.8

4a + 856.8 = 1088.8

subtract 856.8 on both sides

4a = 232

a=58 (58 adults)

153 - 58 = 95 (95 children)

95*$ 5.6 = $532

85 * $ 9.6 = $ 556.8

$532 + $556.8 = $ 1088.8
