First of all we need to formulate two equations.
x = monthly fee per minute
y = monthly fee per minute over 500
500x + 130y = $53.55
500x + 209y = $63.03
Since we know that 500x = $53.55 - 130y we can substitute.
($53.55 - 130y) + 209y = $63.03
79y = 9.48
y = $0.12
Now we can substitute y into the other equation.
500x = $53.55 - 130(0.12)
500x = $53.55 - $15.6
500x = $37.95
So the answer is $37.95 monthly for 500 minutes with an over quota fee of $0.12 per minute.
