Answer:

  • c(m) = 39.95 +0.35m
  • 85 minutes over 500

Step-by-step explanation:

Let m represent the number of minutes used over 500. Then the cost of the cell phone plan is ...

  c(m) = 39.95 +0.35m

__

For a cost of 69.70, the number of excess minutes can be found by solving ...

  69.70 = 39.95 +0.35m

  29.75 = 0.35m . . . . . . . . . subtract 39.95

  29.75/0.35 = m = 85 . . . . divide by the coefficient of m

The number of minutes of usage over 500 is 85.
