Complete the Which is best? row $($F$17$:L$17)$ of the Cost Comparison table on the Cellular worksheet.

Notice that the costs associated with Option $2$ are already calculated in the worksheet.

Write a formula to display "Option $1"$ if the total cost of Option $1$ is less than the total cost of Option $2$ for that month.

If the total cost of Option $2$ is less than the total cost of Option $1,$ display "Option $2".$

Otherwise, display $"$No Difference".

Reuse your formula to determine which option is best for each month and in cell L$17$ to determine which option is best overall.
