Answer provided by our tutors
Let
x = the minutes Nick spoke on weekends
y = the minutes Nick spoke on weekends
This month Nick was billed for 596 minutes:
x + y = 596
The charge for these minutes was $40.47:
0.06x + 0.09y = 40.47
We have the following system of equations:
x + y = 596
0.06x + 0.09y = 40.47
........
........
x = 439 min
y = 157 min
Nick talked 439 minutes in weekends and 157 minutes on weekdays.
