The graph you described represents the cost of Jasper's rental truck as a function of the number of hours he rents it.

- The **flat fee** of $25 represents the starting point (the y-intercept) on the graph when the number of hours (x-value) is 0. This means that no matter how many hours Jasper rents the truck, he will always incur this initial charge.

- The **hourly charge** of $15 represents the slope of the line. This means that for every hour Jasper rents the truck, the total cost increases by $15.

The **rate of change** in this context is the hourly charge, which is **$15**.

So the correct answer to the question about the rate of change is:

**15**
