a$.$ In cell $C7,$ create a formula without using a function that multiplies the sales projection for the first year $($cell C$6)$ by the first growth rate $($cell C$5),$ and adds the sales projection for the first year $($cell C$6)$ to the result to determine the first estimate for $2022.$

b$.$ Use an absolute reference to row $5$ in the reference to cell $C5.$

c$.$ Copy the formula from cell $C7$ to the range $C8$:$C10,$ and then copy the formulas
