An internet service provider offers two plans.
Plan A cost $25 per month and allows unlimited internet access.
CostA = 25m where m is number of months
---------------------------------------------
Plan B cost $12 per month and allows 50 free hours plus 65 cents each addtional hour.
CostB = 12m

How many hours would a customer need to use internet service in order for Plan A to be less expensive than Plan B.
---
25m < 12m + 0.65(h-50)
13m < 0.65h - 32.5
0.65h > 13m + 32.5
h > (13m+32.5)/0.65

a=25
b=12+.65(50-h)
25=12+.65(50-h)
13=.65*50-.65h
h=30
more than 80 hours a month
80/30= more 2hr 40 minutes daily
