Answer provided by our tutors
Let
x = the number of minutes Nick spoke on weekends
y = the number of minutes Nick spoke on weekdays
This month Nick was billed for 595 minutes:
x + y = 595
The charge for these minutes was $34.10:
0.02x + 0.07y = 34.10
We have the following system of equations:
x + y = 595
0.02x + 0.07y = 34.10
