c. How should the principal round to estimate how much more money the school needs to its goal? Explain.

To estimate how much more money the school needs to reach its goal, the principal should follow these steps: 1. **Determine the Goal Amount**: Identify the total amount of money the school aims to raise. 2. **Calculate Current Funds**: Assess how much money has already been raised or is currently available. 3. **Subtract Current Funds from Goal**: Subtract the current funds from the goal amount to find out how much more is needed. \[ \text{Amount Needed} = \text{Goal Amount} - \text{Current Funds} \] 4. **Rounding**: To estimate the amount needed, the principal can round the result to the nearest whole number or to a more manageable figure (like the nearest hundred or thousand) depending on the context. This can make it easier to communicate the need to stakeholders or to plan fundraising efforts. 5. **Consider Context**: When rounding, consider the context of the fundraising efforts. For example, if the amount needed is $1,250, rounding to the nearest hundred would give $1,300, which might be a more practical target for fundraising campaigns. 6. **Communicate Clearly**: When presenting the rounded figure, the principal should explain the rounding process to ensure transparency and clarity in the fundraising goals. By following these steps, the principal can effectively estimate and communicate how much more money the school needs to reach its fundraising goal.
