Hi, I need help with the questions below please.

Compute the time needed for payback for the following example assuming the investment required an up-front capital outlay of $100,000 and the uneven annual cash flows for each year are provided in the table. If an amount is zero, enter "0". For the time needed for payback, enter your answer to one decimal place, if less than one year (i.e. 0.2, 0.5, etc.).

Year	Unrecovered Investment (Beginning of year)	Annual Cash Flow	Time Needed for Payback
1	$100,000	$20,000		1 year
2		30,000		1
3		40,000		1
4		50,000
5		60,000

Total time needed for payback (to the nearest tenth of a year) =________

Average Rate of Return

The average rate of return is another method that does not use present value and is commonly used in making capital investment decisions. Unlike the cash payback method, the average rate of return focuses on income rather than cash flow.

Assume that the investment involves an initial outlay of $100,000 with a five-year useful life and no salvage value under straight-line depreciation. The revenues are as follows: Year 1 - $20,000, Year 2 - $30,000, Year 3 - $40,000, Year 4 - $50,000 and Year 5 - $60,000.

Use the minus sign to indicate a net loss. If an amount is zero, enter "0".

Year		Revenues		Expenses		Net Income
Year 1 Net Income (loss)	=	20,000	-		=
Year 2 Net Income (loss)	=	30,000	-		=
Year 3 Net Income (loss)	=	40,000	-		=
Year 4 Net Income (loss)	=	50,000	-		=
Year 5 Net Income (loss)	=	60,000	-		=

Total Net Income (five years) = $______________
