Answer:
He bought 5 tickets.
Step-by-step explanation:
The cost of buying t tickets is given by the following function:
[tex]c(t) = 24.50t + 9.5[/tex]
If the student spent a total of $132 on tickets, how many tickets did he buy?
This is t when [tex]c(t) = 132[/tex]. So
[tex]c(t) = 24.50t + 9.5[/tex]
[tex]132 = 24.50t + 9.5[/tex]
[tex]24.50t = 122.5[/tex]
[tex]t = \frac{122.5}{24.5}[/tex]
[tex]t = 5[/tex]
He bought 5 tickets.
