Question 549281: You need to choose between two telephone plans for local calls, plan A charges $25 per month for local call, plan B has a monthly fee of $13 with a charge of $0.06 per call. How many telephone calls in a month make plan A a better deal? Answer by TutorDelphia(193) (Show Source):
You can put this solution on YOUR website! Plan A:
$25
Plan B:
Number of calls=n
$13+$0.06*n
Plan B will cost more than Plan A when $13+$0.06*n>$25
$13+$0.06*n>$25
-13 from both sides
$0.06*n>$12
/$0.06 from both sides
n>200
Plan A will be cost less when your number of calls is more than 200 (so 201 or more)
