This should be your easiest problem, to ensure you get full credit on at least one problem and to lower
the overall value of all other problems.
Please make a copy of your ‘Pizza Orders’ sheet and call it ‘Pizza Orders – Copy’. As you move forward
with the remaining problems, you can make any further sheet copies or data manipulation against the
‘Pizza Orders – Copy’ sheet, leaving yourself with a pristine original ‘Pizza Orders’ sheet as a fallback.
