The management of Revco Products is exploring four different investment opportunities. Information on the four projects under study follows:

Project number
1 2 3 4
Investment required $(500,000) $(450,000) $(220,000) $(470,000)
Present value of cash inflows at 12% discount rate 568,080 522,000 266,400 616,650
Net present value $ 86,060 $72,000 $46,400 $146,650
Life of the project 9 years 18 years 9 years 6 years
Internal rate of return 16% 15% 17% 22%
Because the company's required rate of return is 12%, a 12% discount rate has been used in the present value computations above. Limited funds are available for investment, so the company can't accept all of the available projects.

Required:

1. Compute the project profitability index for each investment project. (Round your answers to 2 decimal places.)
