13. Estimate the gross profit for 2021 as follows: a. In cell C15, create a formula without using a function that subtracts the vendor cost (cell C7) and the shipping cost (cell C9) from the sales price (cell C8), and then multiplies the result by the projected number of units for sale in 2021 (cell C10). Use absolute references to each cell in the formula. Copy the formula from cell C15 to the range D15:115 to complete the estimates for 2021. b. C. 14. Complete the growth estimates for the years 2022 to 2025 as follows: a. In cell C16, create a formula that adds 1 to the growth rate (cell C14) and multiplies the result by the estimated profit from 2021 (cell C15). b. Use an absolute row reference to cell C14. Copy the formula from cell C16 to the range C17:C19 to enter the first estimates for 2023-2025. Copy the formulas from the range C16:C19 to the range D16:119 to enter the remaining sales projections.
