Question

A long distance phone call between two cities costs ​$1.08 for 18 minutes. what is the rate in cents per​ minute?

Answer 1

First, we find the cost for 1 minute.
So, we need to divide the total costs by the total times.
$1.08 ÷ 18 minutes = $0.06

Then, we change the rate in cents per minute.
$0.06 = 6 cents per minute
