Timothy Hunt · Answer 1

The first thing we must do for this case is write both linear equations.

We have then:

For plan A:

y = 0.04 (x-500) + 40

For plan B:

y = 0.02 (x-800) + 60

Solving the equations we have:

x = 1200 minutes

y = 68 $

Answer:

both options cost the same amount in:

x = 1200 minutes

The cost is:

y = 68 $
