1. For what number of minutes of long distances calls will te cost for the two plans be same? What will be the cost for each plan?

cost of plan 1: 20+0.05m (where m is the number of minutes you make long distance calls
cost of plan2: 5+0.10m
when are they equal?
when 20+0.05m=5+0.1m
solve for m:
20-5=0.1m-0.05m
15=0.05m
m=15/0.05
m=300 min
the cost of both plans at 300 min is 20+0.05 x 300=$35
