A phone company offers two monthly plans.
Plan A costs $15 plus an additional $0.15 for each minute of calls.
Plan B costs $26 plus an additional $0.13 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?
~~~~~~~~~~~~~~~~~~~ 


    15 + 0.15t = 26 + 0.13t  (where t is the amount of calling time)


From this equation


    t = %2826-15%29%2F%280.15-0.13%29 = 550 minutes.


The common costs  is  15 + 550*0.15 = 97.50  dollars.

Solved.
