Question

A phone company offers two monthly plans. Plan A costs $18 plus an additional $0.10 for each minute of calls. Plan B costs $22 plus an additional $0.08 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 1

>18+0.10 times 40= $22 and add 0.10 times 4=0.40=$22.40
>You need to get 0.08 into a multiple of ten so 8 times by 5=0.40
>go back to the plan A =$22.40- 44 minutes of calls.
>go back to the plan B =$22.40- 5 minutes of calls
