Answer:

He bought 5 tickets.

Explanation:

The cost of buying t tickets is given by the following function:


c(t) = 24.50t + 9.5

If the student spent a total of $132 on tickets, how many tickets did he buy?​

This is t when
c(t) = 132. So


c(t) = 24.50t + 9.5


132 = 24.50t + 9.5


24.50t = 122.5


t = (122.5)/(24.5)


t = 5

He bought 5 tickets.
