Answer:
It would cost $23.75
Step-by-step explanation:
The first step is two take the price of an adult ticket and multiply it by 2 since there are going to be two adults attending:
9 x 2 = 18
Next, we add the price of the child's ticket to that of the parents:
18 + 5.75 = 23.75
Finally, we know that the currency is USD so we add that to get our final answer:
$23.75
