let
x = the minutes Niick talked on weekends
y = the minutes Niick talked on weekdays
This month Nick was billed for 535 minutes:
x + y = 535
The charges for these minutes was $38.78:
0.05x + 0.08y = 38.78 multiply both sides by 100
5x + 8y = 3878
by solving the system of equations:
x + y = 535
5x + 8y = 3878
we find:
x = 134 min
y = 401 min
