Make corrections to the cash flow tabs and the cost and investing tabs on the attached excel worksheet. below is the recommendations from my professor. thanks for the help. Cash Flow tab: More depth and critical thinking is needed to mine the data for real actionable intelligence upon which to make a judgment. Cost and Investing tab: Question 7: Use standard gross margin of 25.5%. Question 8: This question should use the price determined in Question 6 to determine whether there is a positive contribution margin. Question 9: At $1,050,000 is there still a positive contribution margin that can cover at least some of the ongoing fixed cost? Question 10: Incorrect. BE = total fixed cost/contribution margin per unit
