You can put this solution on YOUR website!
c = 0.05m + 4.95
:
The graph of c has m plotted on the x axis, therefore
:
we set m = 0 to find the y intercept
:
c = 0.05 * 0 + 4.95
:
***********************
the y intercept is 4.95
***********************
:
c = 0.05 * 140 + 4.95 = 11.95
:
*********************************************
The cost for 140 minutes in a month is $11.95
