Answer:

the graph will describe 13x+15 if the cost per audio book goes up by $1.00.

Step-by-step explanation:

This happens because the coefficient to x is 12 before the change. If the change is the cost per audio book going up by one dollar, the coefficient changes to 13. The initial joining fee is the same ($15.00).
