Last year, gena’s food cart business was $225 in debt. this year, the debt has tripled. which expressions show how much gena’s business is currently in debt?

Frequently, and even historically, the creation and use of negative numbers has been associated with debts. To denote a certain amount of debt, we add a negative sign before the amount to indicate the fact that it's a debt.

Here, Gena's food cart is $225 in debt, so we could indicate that with the negative number -225. If we're tripling the debt, we're going to be multiplying that debt by 3, which corresponds to the expression -225 x 3. If you're adding onto your debt, you're naturally going to still be in debt, so we leave the negative sign on and multiply 225 and 3, obtaining -225 x 3 = -675. Gena's food cart is now $675 in debt.
