Question

-Using the properties of real numbers (laws of signs) performs the following arithmetic operations. 1. A person owes your credit card $6000 and makes a payment of $2500 with it, if the bank charges $500 in interest and fees, what is the new balance on the card?

Answer 1

You have the following information:

- The original amount of money in the credit card was $6,000.

- A payment of $2,500 was made with the credit card.

- The bank charges $500 in interest and fees.

Based on the information given, you must subtract $2,500 and $500 from $6,000.

Then, you can set up the following arithmetic operation:

`6,000-2,500-500`

Add the numbers that have the same sign:

`=6,000-3,000`

Finally, solve the subtraction:

`=6,000-3,000=3,000`

(Notice that, since the sign of the larger value is positive, the result is positive)

Therefore, the new balance of the card is $3,000
