Question

At the movie theatre, child admission is 5.40 and adult admission is 8.90On Monday, three times as many adult tickets as child tickets were sold, for a total sales of \$706.20 How many child tickets were sold that day?

Answer 1

Step 1

Let the number of adult tickets = 3m

The number of child tickets = m

Step 2

`\begin{gathered} Total\text{ cost of adult tickets = 26.7m} \\ Total\text{ cost of child tickets = 5.4m} \end{gathered}`

Step 3:

Total sales = $706.20

`\begin{gathered} 26.7m\text{ + 5.4m = 706.2} \\ 32.1m\text{ = 706.2} \\ m\text{ = }(706.2)/(32.1) \\ \text{m = 22} \end{gathered}`

Number of child tickets that were sold that day = 22
