This is the hardest question we'll for me

12.6

Step-by-step explanation:

a. 315 - 25 = $290

b. After each payment, the amount owed decreases. Therefore, the balance decreases.  

second part of this: write equation for calculating the amount owed a for any number of payments n                      $      $25(n-1)  =a

I cant draw a graph on here for you, but as n increases, then a decreases

d. as n increases by 1, how does a change?   A decreases by $25 each time n increases by one

e. He will need to make 12.6 payments
