Consider the following cash flows of two mutually exclusive projects for Spartan Rubber Company:Year Dry Prepreg Solvent Prepreg0 -$1,740,000 -$770,0001 $1,104,000 $395,0002 $908,000 $640,0003 $754,000 $398,000Assume the discount rate for Spartan Rubber Company is 11 per cent.1) What is the payback period for each project?2) What is the NPV for each project?3) What is the IRR for each project?4) Calculate the incremental IRR for the cash flows.

Suppose life expectancy in years (l) is a function of two inputs, health expenditures (h) and nutrition expenditures (n) in hundreds of dollars per year. the production function is upper l equals ch superscript 0.40 baseline upper n superscript 0.60l=ch0.40n0.60. beginning with c = 1, a health input of $400400 per year (hequals=44) and a nutrition input of $400400 per year (nequals=44), show that the marginal product of health expenditures and the marginal product of nutrition expenditures are both decreasing. the marginal product of health expenditures when h goes from 44 to 55 is nothing, and the marginal product of health when h goes from 66 to 77 is nothing. (round your answers to three decimal places.)
