Question

A telephone costs $0.05 per minute with a fixed fee of $2. Another costs $0.10 per minute with a fixed fee of $1.50. How many minutes would you have to call for the phone calls to cost the same?

Answer 1

10 minutes for them to cot the same.

Explanation:

First, you have to equal them to each other.

0.05m + 2 = 0.10m + 1.50

Subtract 0.05m from both sides.

2 = 0.05m + 1.50.

Next, subtract 1.50 from each side.

0.50 = 0.05m

FInally, divide 0.05 on both sides.

10 = m
