The ace telephone co. charges a flat monthly fee of $22.00 for a telephone line and $0.20 per minute for long distance calls. if
you make 25 minutes of long distance calls per month, what will it cost?
1 answer:
Y = 0.20x + 22...x = number of calls, y = total bill per month
if 25 minutes of calls were made.....x = 25
y = 0.20(25) + 22
y = 5 + 22
y = 27.....so the monthly bill is $ 27
