Answer:
X = 9 months
Step-by-step explanation:
To solve the number of months when the cost of each payment
are the same, you should equate the two cost. First establish the equations
Let A be the cost of first payment method
B is the cost of the second payment method
X is the number of months
A = 38x + 15
B = 31x + 78
38x + 15 = 31x + 78
7x = 63
X = 9 months
