Step-by-step explanation:
Let x = number of child tickets sold.
Cost of x child tickets is x * 5.30 = 5.3x.
"three times as many adult tickets as child tickets were sold"
Number of adult tickets sold: 3x
Cost of 3x adult tickets is 3x * 8.40 = 25.2x
Cost of all tickets is 5.3x + 25.2x = 30.5x
Cost of all tickets is $1189.50
30.5x = 1189.5
x = 1189.5/30.5
x = 39
