total expense per unit sold calculation In cell B$17$ does not produce a divide by zero error.Modify the formula in cell B$17$ as follows:a$.$ Add the IFERROR function to the formula in cell B$17.$b$.$ Use "Divide total expenses by units manufactured" as the message to display in case of an error$\mathrm{.}19.$ Benicio has already calculated that the gross profit for the new product could be nearly$$295,000$ based on a unit price of $$159\mathrm{.}99$ and unit sales of $22,000.$ He wants to see how the gross profit changes if the price or unit sales are different.Create a two$-$variable data table as follows to calculate gross profit as the price and unit sales change:a$.$ For the range D$4$:$9,$ create a two$-$variable data table using the price per unit $($cell B$6)$ as the Row input cell.b$.$ Use the units sold $($cell B$5)$ as the Column input cell.
