At the movie theatre, child admission is $5.70 and adult admission is $9.75 . On Friday, 173 tickets were sold for a total sales

storchak [24]

Answer: 94 child tickets

<u>Step-by-step explanation:</u>

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

<u> -5.70x - 5.70y</u> = <u>-986.10</u>

4.05y = 320.00

<u> ÷4.05 </u> <u>÷4.05 </u>

y = 79

x + y = 173

x + 79 = 173

x = 94
