Question

A telephone company charges $40.00 per month for cell phone usage that does not exceed 750 minutes. Any usage over 750 minutes is charged at a rate of $0.45 a minute. If a customer uses a cell phone for 977 minutes in a month, how much will that monthly cell phone bill be?

Answer 1

$142.15

977-750 = 227
227 • .45 = 102.15
102.15 + 40 (monthly payment) = 142.15 :)
