Complete the table above to calculate NPV for commodity A and B without using NPV function. Assume a discount rate of 15%. Question 3.b. Use NPV function to calculate net present values for commodity A in Cell N23 for commodity B in Cell N25. Assume a discount rate of 15%. NPV for A 33,514 NPV for B -10,068 Question 3.c. Based on your NPV calculation, which commodity would you produce and why? Answer 3.c. The commodity to produce would be commodity A. As Commoity B is giving a lower present value of $10,068 compared to commoidty A which is 33,514
