Explanation:
The amount of money that the students will pay back with the fundraiser (D) would be half of the current debt (d) since debt is represented as a negative but the fundraiser needs to be a positive since it is money gained we would divide by -2
D =
![(-d)/(-2)](https://img.qammunity.org/2021/formulas/mathematics/high-school/3z7otxhc7caxrrm857uts3ryll8p4fcwlh.png)
This equation shows the debt that will be repaid through the fundraiser which would be exactly half of the current debt.
