Answer provided by our tutors
Let
f = the fixed monthly charge
m = the charge for each pay-per-view movie
In January the $44 bill included 4 pay-per-view movies:
f + 4m = 44
In February the $54.50 bill included 7 pay-per-view movies:
f + 7m = 54.50
We have the following system of equations:
f + 4m = 44
f + 7m = 54.50

........
f = $30
m = $3.50
The fixed monthly charge is $30.
The charge of each pay-per-view movie is $3.50.
