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

Explanation:

18 + .10x = 22 + .08x

.04x=5

x = 22/0.08 = 275 minutes, is the number of minutes the two plans cost the same

18 + .10*125 = $30.5 is the cost when the two plans cost the same
