Assume a MARR of 4.0%. Note: All values shown are in 1000s, thus -80 represents -80,000. Compute the IRR, ERR and DBPB for the investment represented by the following cash flow table:

Year	0	1	2	3	4	5	6	7	8	9
Revenue	0	+1350	+1300	+1250	+1200	+1350	+1300	+1250	+1200	+1150
O&M	0	-80	-80	-80	-80	-80	-80	-80	-80	-80
Capital costs and other major costs	-8000				-400					+25
