c) Solve the system of equations to determine how many movies you must rent from each company to have equal bills.
***DO NOT just give an answer. You must show your work and explain what you did.***

A = 129 + 7.99 n
Y = 144 + 4.99 m
if Y = A and m = n then
129 + 7.99 n = 144 + 4.99 n
3 n = 15
n = m = 5 of either
put that back as n in the A equation or as m in Y
Y = 144 + 4.99 * 5
