2	30,000	35,000
3	30,000	40,000
4	30,000	25,000

(i) The projects are mutually exclusive and there is no capital constraint.

(ii) The projects are independent and there is no capital constraint.

(iii) The projects are independent and there is a total of $100,000 of financing for capital outlays in the coming period.
