Question

31. A student brought concert tickets online. The total cost, c, in dollars, of t tickets can be found using the funtion below

Answer 1

Answer:

He bought 5 tickets.

Step-by-step 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

$c(t) = 24.50t + 9.5$

$132 = 24.50t + 9.5$

$24.50t = 122.5$

$t = \frac{122.5}{24.5}$

$t = 5$

He bought 5 tickets.
