To write a formula with absolute cell references, you need to use the dollar sign ($) before the column letter and row number of the cell reference you want to make absolute. This will ensure that the cell reference does not change when you copy the formula to other cells.

For example, if your current quotas are in cell A1, and you want to determine the projected quotas at 10%, 15%, and 20% of the current quotas, you can use the following formulas:

1. For 10% of current quotas:
   Code:

   = $A$1*10%

2. For 15% of current quotas:
   Code:

   = $A$1*15%

3. For 20% of current quotas:
   Code:

   = $A$1*20%

Here's a step-by-step guide on how to write these formulas:

1. Click on the cell where you want to display the projected quotas for 10% of the current quotas.
2. Type the equal sign (=) to start the formula.
3. Click on the cell that contains the current quotas (in this case, cell A1).
4. Type the multiplication sign (*) to indicate that you want to multiply the current quotas by a percentage.
5. Type the percentage sign (%) and the number 10 to indicate that you want to calculate 10% of the current quotas.
6. Press Enter to complete the formula.

The formula should now display the projected quotas for 10% of the current quotas. To calculate the projected quotas for 15% and 20% of the current quotas, you can repeat the same steps, but change the percentage in step 5 to 15% and 20%, respectively.

Remember to use absolute cell references (with the dollar sign) for the cell that contains the current quotas (in this case, cell A1), so that the formula will always refer to that cell even when you copy it to other cells.
