The regular price of a child's entry ticket to a water park is $9 less than that for an adult's. The park offers half off all en

ser-zykov [4K]

The regular price of a child's ticket is $51

Explanation

If $x$ represents the regular price of an adult ticket, then the regular price of a child's ticket $=(x-9)$

Given equations is: $132=\frac{1}{2}x+2(x-9)$

Solving the above equation, we will get...

$132=\frac{1}{2}x+2(x-9)\\ \\ 132=\frac{1}{2}x+2x-18 \\ \\ 132=\frac{5}{2}x-18\\ \\ 132+18=\frac{5}{2}x\\ \\ 150= \frac{5}{2}x\\ \\ 300=5x\\ \\ x= \frac{300}{5}=60$

So, the regular price of a child's ticket $=x-9=60-9= 51$ dollar.
