525/15 = 35 they would need to sell 35 tickets for there concert to cover the cost of the gym. <span />
For this case we have the following function:

By definition, the average rate of change is given by:

We evaluate the function for the given values:
For x = 7:

For x = 14:

Then, replacing values we have:
Answer:
the average rate of change from x = 7 to x = 14 is:
a. 23.22
$48.32* (15/100)
= $7.25.
The final answer is $7.25~
