Solution

Step 1

Let the number of adult tickets = 3m

The number of child tickets = m

Step 2

[tex]\begin{gathered} Total\text{ cost of adult tickets = 26.7m} \\ Total\text{ cost of child tickets = 5.4m} \end{gathered}[/tex]

Step 3:

Total sales = $706.20

[tex]\begin{gathered} 26.7m\text{ + 5.4m = 706.2} \\ 32.1m\text{ = 706.2} \\ m\text{ = }\frac{706.2}{32.1} \\ \text{m = 22} \end{gathered}[/tex]

Number of child tickets that were sold that day = 22
