Answer 1

Each burglury cost 4000, One officer saves 40 burgluries hence cost of 40*4000=160,000

1st officer will reduce property loss by $160,000

Additional officer added will reduce property loss by half of previous case hence 2nd officer will reduce property loss by $80000

Similarly 3rd officer will reduce property loss by $40000 and 4th will reduce by $20,000.

Using Conventional method to calculate number of officers

Cost of recruting officers= Total Property loss saved

40000*n=160000*1/2+160000*1/4+...+...

40000*n=160000(1/1-0.5)=320000

n=8

Hence * officers should be employed
