The difference between the first company and the other is that the first charges $1 less per movie than the second , but charges $15 more than the second as well.
To awnser this problem and equal the charges in bth companies we just need to cancel out the $15 the first company charges more than the second.
As we pay more $1 each movie in the first , we would need to view 15 movies to equalize the charges from both companies :
x= 15 if we want to equalize the charges
f(x) = 4.95(15) + 40
f(x) = 74.25 + 40 = 114.25
g(x) = 5.95(15) + 25
g(x) = 89.25 + 25 = 114.25
Awnser: We would need to view 15 pay per view to equalize the bills from both companies
