Question 558272: This is a story problem that i just dont understand
If a new cell phone co. offers a cellular plan that charges 29.95 per month and $.05 per min after the first 1200 mins. write an equation for the cost as function of the number of mins used.
This is the only thing that I can come up with but I dont think its right
(.05x T=y)= 29.95+y
T= would be the mins over the 1200
Thanks for all of your help

If a new cell phone co. offers a cellular plan that charges 29.95 per month and $.05 per min after the first 1200 mins.
write an equation for the cost as function of the number of mins used.
:
Let m = no. minutes
C(m) = .05(m-1200) + 29.95
:
Of course this would only be valid if the user used 1200 min or more
