−$30 could represent withdrawing $30 from an account. (Yes)

+125 could represent 125 feet below sea level. (Yes)

−15 could represent the loss of 15 yards on a play. (Yes)

+80 could represent a gain on stock. (Yes)

0 feet could represent the altitude of a city that is located at sea level. (Yes)

Answer 2

Yes, No, Yes, Yes, Yes!

Explanation:

First Question:

That is correct because if you have $0 in your bank account and you withdraw $30 you will have -$30!

(And you are in debt which everyone hates!)

Second Question:

No, because that would be 125 above ground. You would need to say -125 instead of adding.

Third Question:

Yes! Let's say in the football game you had 70 yards, subtracting the 15 yards which you supposedly had lost would result in 55 yards therefore proving the fact that you did not progress but did the exact opposite!

Fourth Question:

Yes, because you are gaining more on your stock. This results in you getting more of a share in a company or product.

Fifth Question:

To be honest, I don't know if this: "0 feet could represent the altitude of a city that is located at sea level." is a question but I will answer it nonetheless!

Yes, because before right where the sea "starts" is what is called point 0. Meaning that, you are located at sea level!
