First we will calculate the distance AB.

If C is 5/9 of the distance, mathematically speaking that means:

R: The coordonate of C is 15.
Smart Dot, multiply the cost per hour by number of hours (t) and add to the monthly fee:
C = 0.50t + 12
Communication plus: Multiply the cost per hour by number of hours (t)
C = 2.50t
