You have $20 in your wallet. you are out shopping at a video store with a friend, and see a dvd you want, but it costs $32.
a. your friend loans you enough money to you pay for it. what are your available funds after you buy the dvd

Given:

20$

DVD cost = 32$

Friend’s loan = 12$ (since he loaned you enough money to be able to pay for the DVD)

Find:

available funds after you buy the DVD = ?

Solution:

First, we add your current funds with the money your friend loaned you:

20$ + 12 $ (we will assume this amount since the problem states that he loaned you just enough money to pay for the DVD) = 32$

Next, we subtract the total amount of the DVD cost to the total amount of money you have right now:

$32 (DVD cost) - $32 (your total funds) = $0

Therefore, your available funds after buying the DVD is $0. But if we will take into consideration the amount you loaned from your friend by subtracting it to your remaining funds, then you’ll have $0 - $12 = $-12, which is your debt.
