Question

A cell phone company charges a flat rate of $2.50 per month, with an additional charge of $0.15 per minute. How many minutes did Laura talk on her cell phone if her monthly bill was $72.25?

Answer 1

465 minutes

Explanation:

First things first, you have to make an equation! It would be...

2.50+0.15m=72.25

Keep in mind that m stands for minutes.

Now let's solve it!!

First let's subtract 2.50 from both sides.

0.15m=69.75

Now, let's divide 0.15 on both sides!

m= 465

465 minutes!!

Hope this helped!! :D
