How many minutes would the charge be the same for both the plans?
One phone plan charges a $20 monthly fee and $0.08 per minute on every phone call made. Another phone plan charges a $12 monthly fee and $0.12 per minute for each call.
200 minutes-let m represent the minutes of the phone calls. the monthly charge for the first plan is 20 + 0.08m. the monthly charge for the second plan is 12 + 0.12m. when the monthly charges are the same, 20 + 0.08m = 12 + 0.12m. solve for m to find the number of minutes both plans have the same rate.10 + 0.08m - 0.08m = 12 + 0.12m - 0.08m 20 = 12 + 0.04m 20 - 12 = 12 + 0.04m - 12 8 = 0.04m so m = 8/0.04 = 800/4 = 200 minutes
