Nick's telephone company charges $0.04 per minute for weekend calls and $0.07 per minute for calls made on weekdays. This month Nick was billed for 606 minutes. The charges for these minutes was $38.88. How many minutes did he talk on weekends and how many minutes did he talk on weekdays?
Answer provided by our tutors
let 'x' represent the number of weekend minutes, then '606-x' represents the number of weekday minutes
38.88 = 0.04x + 0.07(606-x)
solving for 'x' we have x=118
606-118 = 488
Nick used 118 weekend minutes and 488 weekday minutes
