Final Answer:
In cells D10, D18, and D25 of the Marketing Budget Plan worksheet, use the formula =SUM(D$4:D9) for D10, =SUM(D$4:D17) for D18, and =SUM(D$4:D24) for D25 to gather the sum of the data above in each respective cell.
Step-by-step explanation:
To calculate the sum of data in cells D10, D18, and D25, you an use the SUM formula in Excel. In cell D10, the formula =SUM(D$4:D9) is applied. This formula sums the range of cells from D4 to D9, effectively adding up the data above D10. The dollar sign before the row number in D$4 ensures that the range remains constant when copied to other cells, anchoring the starting point of the sum.
Similarly, in cell D18, the formula =SUM(D$4:D17) is utilized. This formula sums the data from D4 to D17, capturing the values above D18. Again, the dollar sign in D$4 ensures that the starting point of the sum does not change when the formula is copied to different cells.
In D25, the formula =SUM(D$4:D24) is implemented. This sums the data in cells D4 to D24, including all values above D25. The use of dollar signs in the range D$4:D24 maintains the consistency of the formula, allowing it to be easily replicated while ensuring the correct data is included in the sum.
By employing these formulas, you create a dynamic and efficient way to calculate the sum of data above specific cells in the Marketing Budget Plan worksheet, simplifying the budgeting process.
