You would like to purchase a monthly package from and Internet Provider.
States online charges $2.95 monthly and then 30 cents every hour you use the service.
Big Neat Online charge $4.95 monthly plus 10 cents every hour you use the service.
Which service would be the cheapest,if you average 51 hours a month online?:confused:

Then the costs can be calculated by:
States online: C = 2.95 + 0.3*t
Big Neat online: C = 4.95 + 0.1*t
Now plug in t = 51 and you'll get:
SO: C(51) = $18.25
BN: C(51) = $10.05
By the way: At t = 10 h both providers want $5.95
