Question 1090638: One cell phone plan charges $17.50 per month plus $0.17 per minute used. A second cell phone plan charges $32 per month plus $0.07 per minute used. Write and solve an equation to find the number of minutes you must talk to have the same cost for both calling plans. Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! Let n be the number of minutes used. Then, to be equal:
17.5+.17n=32+.07n
1750+17n=3200+7n
10n=1450
n=145 minutes before the two plans are equal.
