14. In cell B14, create a formula without using a function that adds 1 to the value in cell B12 and then multiplies the result by the value in cell B13. Update the reference to cell B12, from a relative reference to a mixed reference by making an absolute reference to row 12. Copy the formula from cell B14 to the range B15:B17 and then copy the formulas from the range B14:B17 to the range C14:H17.
