Question

Josie wants to buy Internet access. One service provider charges a flat rate of $34.95/month. A second charges $25/month plus 33 cents/h. For what number of hours per month should Josie choose the flat rate?

Answer 1

$34.95/month

(34.95/1 mo)(x mo)  =  

$25/month plus 33 cents/h

25.00 + (.33/hr)(number of hours)

25.00 + (.33/hr)(y)

(34.95/1 mo)(x mo) = 25.00 + (.33/hr)(y)

Let x be 1

34.95 = 25.00 +(.33)(y)

9.95 = .33y

y = 30.2 hours

At 30.2 hours of use, the costs will be the same.  At greater than 30.2 hours of use, the flat rate only plan will be cheaper.
