Question

Mat bought a phone for $100. He has to pay $30 per mouth. If he has paid $640 in total, how many mouth has he had the phone?

Answer 1

18 months.

Explanation:

I am assuming the $100 dollars was the initial purchase price.

If that is true we subtract from the $640 total payed:

640 - 100 = $540 dollars.

Next we divide the 540 by the monthly $30 dollar rate:

540 / 30 = 18

Check our work:

18 months @ 30/month = 540 + 100 dollar down payment = 640.

Answer 2

Answer: 18 months

Explanation:

$640-$100purchse of phone=$540
