Nick's telephone company charges
$0.01
per minute for weekend calls and
$0.08
per minute for calls made on weekdays. This month Nick was billed for
627
minutes. The charge for these minutes was
$26.99.
How many minutes did he talk on weekends and how many minutes did he talk on weekdays?
Answer provided by our tutors
Let
x = the minutes talked on weekends
y = the minutes talked on weekdays
This month Nick was billed for 627 minutes:
x + y = 627
The charge for these minutes was $26.99:
0.01x + 0.08y = 26.99
By solving the system of equations:
x + y = 627
0.01x + 0.08y = 26.99
........
........
x = 331 min
y = 296 min
Nick talked 331 minutes of weekends and 296 minutes on weekdays.
