b. Using the formula,find the total cost of an 8-minute call?
when you solve this can you make sure you explain how you get the answer because i really need to know how to do it when i take my test Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! m is the total minutes
(m - 3) is the minutes excluding the first three minutes
T = .80 + .20(m - 3)
With m = 8
T = .80 + .20(8 - 3)
T = .80 + 1.00
T = $1.80
