Question

A cell phone company charges $15 for 100 minutes. What is the cost per minute? Round to the nearest cent.

Answer 1

Answer:

15 cents

Step-by-step explanation:

We can solve this by unitary method :

For 100 minutes --> $15

∴ For 1 minute --> $15/100 => $0.15

As 1 dollar = 100 cents

$0.15 = 100*0.15 => 15 cents
