Final answer:
To find the cost of admission for the family, multiply the cost per person by the number of people in the family. The total cost for the family is $39.75, so the answer is none of the above.
Step-by-step explanation:
To find the cost of admission for the family, we need to multiply the cost per person by the number of people in the family. There are 2 adults and 1 child in the family. The cost for each adult is $15.75 and the cost for the child is $8.25.
So, the cost for the adults is $15.75 x 2 = $31.50.
The cost for the child is $8.25 x 1 = $8.25.
Adding the costs together, the total cost for the family is
$31.50 + $8.25 = $31.50+8.25
=$39.75.
Therefore, the correct answer is none of these.
