Question 1168127: A phone company offers two monthly plans. Plan A costs $11 plus an additional $0.12 for each minute of calls. Plan B costs $17 plus an additional $0.10 for each minute of calls.
For what amount of calling do the two plans cost the same?
What is the cost when the two plans cost the same?
$ Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! 11+0.12m=17+0.10m is the equation needed, a linear equation with a constant monthly cost and a variable of minutes used
0.02m=6
m=300 so 300 minutes.
then A is $11+$36 or $47 and B is $17 + $30 or $47.
