Which of the following is a real world problem that could be solved with the sum -22+9

One real-world problem that could be solved with the sum -22 + 9 is a financial situation.

For example, if someone owes $22 and then receives a payment of $9, they can calculate the sum -22 + 9 to determine their remaining debt or balance. In this case, the sum would be -13, indicating that they still owe $13 after receiving the payment of $9.

One real-world problem that could be solved using the sum -22 + 9 is calculating the change owed after making a purchase. If you have a bill of $22 and you give the cashier $9, you can calculate how much change you should receive by subtracting $9 from $22.
