enter formulas in all cells that contain question marks.

For example, in cell C18 enter the formula "= B6".

After entering formulas in all of the cells that contained question marks, verify that the dollar amounts in both the traditional and contribution format income statements match the numbers in Exhibit 1-7.

Check your worksheet by changing the variable selling cost in the Data area to $900, keeping all of the other data the same as in Exhibit 1-7. If your worksheet is operating properly, the net operating income under the traditional format income statement and under the contribution format income statement should now be $700 and the contribution margin should now be $4,700. If you do not get these answers, find the errors in your worksheet and correct them.
