Answer 1

Has Trevor never heard of unlimited minutes?

Answer 2

Anyway, here's how you solve it...

Answer 3

Equation corresponding to Cell Plus Plan:
$25.00+($0.06)m=Total Cost
Equation corresponding to Cell Best Plan:
$30.00+($0.05)m=Total Cost
where m is number of minutes used.

To find out where they intersect, you set the equations equal to each other and solve for m:
$25.00+($0.06)m=$30.00+($0.05)m
(0.06-0.05)m=30-25
0.01m=5
m=5/0.01=500 minutes.

Hope that helps.
