Nick's telephone company charges $0.02 per minute for weekend calls and $0.09 per minute for calls made on weekdays. This month Nick was billed for 542 minutes. The charge for these minutes was $37.16. How many minutes did he talk on weekends and how many minutes did he talk on the weekdays?
Answer provided by our tutors
let 'x' represent the number of minutes Nick talked on the weekend, then '542-x' represents the number of minutes he talked on weekdays and we have this equation:
37.16 = 0.02x + 0.09(542-x)
solving for 'x' we have x=166
542-166 = 376
Nick talked for 166 minutes over the weekend and 376 minutes during weekdays
