Final answer:
The family purchased 6 tickets. This was determined by subtracting the parking fee from the total amount spent and then dividing by the cost per ticket. The correct answer is option: a) 6 tickets
Step-by-step explanation:
To find out how many tickets the family purchased, we need to solve the equation 64 = 9.50n + 7, where n represents the number of tickets purchased.
- First, subtract the parking fee from the total spent to find the total spent on tickets: 64 - 7 = 57.
- Next, divide this amount by the cost per ticket to find the number of tickets: 57 ÷ 9.50 = 6.
Therefore, the family purchased 6 tickets.
