Need help completing this chart. Specifically, please provide the formula that you used to calculate each box with an "X" and the numbers that you used in each formula so I can follow them. Please label which formulas you used to calculate each box with an "X" in it. Since many of these have to be backed into. Please provide step by step so I know which ones you calculated first to back into the next one. Also, it must be possible to use a re-arrangement of the profit formula to solve some of these too, but I cannot figure out how to rearrange that formula. Thank you for your help.
