Excel formulas are expressions used to perform computation.
The formula in Excel is: =($B$6 - $B$5 - $B$7)* $B$8
<h3>How to determine the formula</h3>
From the question, we are to:
- Subtract B5 and B7 from B6
- Use absolute style referencing
To use the absolute reference in Excel cells, we have to include the dollar "$" sign.
This means that: a cell A1 will be written as: $A$1;
So, the formula to enter in cell B13 is:
=($B$6 - $B$5 - $B$7)* $B$8
