Answer: 94 child tickets
Explanation:
Let x represent child tickets
Let y represent adult tickets
Cost Equation: 5.70x + 9.75y = 1306.10
Quantity Equation: x + y = 173
Solve the system of equations using the elimination method:
Multiply the Quantity Equation by -5.70
5.70x + 9.75y = 1306.10
-5.70x - 5.70y = -986.10
4.05y = 320.00
÷4.05 ÷4.05
y = 79
x + y = 173
x + 79 = 173
x = 94
