Answer provided by our tutors
let
x = the number of minutes Nick talked on weekends
y = the number of minutes Nick talked on weekdays
this month Nick was billed for 567 minutes:
x + y = 567
Nick's telephone company charges $0.02 per minute for weekend calls and $0.07 per minute for calls made on weekdays. The charges for these minutes was $27.49.
0.02x + 0.07y = 27.49
by solving the system of equations
x + y = 567
0.02x + 0.07y = 27.49
we find
x = 244 min
y = 323 min
