Determine (a) the rae of retum on the incremental cash Hows and (B) which one should be selected if the company's MIARR is 25\% per year. Altermative X3 requirss the larger initill investmeat. 8.14 Standby power for pumps at water distribution booser stations can he provided by either gasoline. or diesel-powered enpines.
