Question 431492
Plan 1: $4.95 per month plus $0.07 per minute
Plan 2: $0.10 per minute
Cost of plan 1 = $4.95 + 0.07t
Cost of plan 2 = 0.10t
where t is the time in minutes
Set the costs equal:
4.95 + 0.07t = 0.10t
Solve for t:
0.03t = 4.95 -> t = 165
So the plans cost the same at 165 minutes.
If you prefer to work with whole numbers, you could use cents instead of dollars.
