Answer: F4
Explanation:
Absolute reference means that we can use a formula for a cell in a Excel and that formula for that particular cell will not be changed even if we copy or drag that formula to some part of the cell.
Excel offers us with the solution of applying formulas to different part of the cells which are indicated by the $ sign. So as in the question Ellen as she is expecting a 3% raise net year in her monthly column, So she can use absolute reference. She enters .03 which is 3 divided by 100 in the monthly income column. So in that column she has to type = for the formula to begin. Then the formula which is .03 and followed by F4 which is used to make the cell D2 absolute reference.
So next time upon referencing cell D2, we would get the value according to the formula.
