GreenWave Technologies receives an unexpected bill of $⁢20,000 How should you update the spreadsheet to calculate the new net profit? Assume revenue is in cell B4, expenses are in cell B5, and net profit is calculated in cell B6.

An unexpected bill increases expenses by $20,000, so update B5 from $400,000 to $400,000 + $20,000 = $420,000. Keep revenue in B4 unchanged, and leave the net profit formula in B6 as =B4-B5. Therefore, choice B is correct.
