Answer: Company B
Step-by-step explanation:
Current company:
Average time = 40 minutes
Cost = Average time x researcher cost
= 40 x $2
= $80
= $5
Company A:-
Company A will reduce the current average time by 10 minutes
Average time = 40 - 10
= 30 minutes
Cost per search = $3.50
Cost = Average time x Researcher cost + cost per search
= 30 x $2 + $3.50
= $63.50
= $6.29
Company B:-
Company B will reduce the current average time by 12 minutes
Average time = 40 - 12
= 28 minutes
Cost per search = $3.60
Cost = Average time x Researcher cost + cost per search
= 28 x $2 + $3.60
= $59.60
= $6.71
The revenue per dollar of input of:
Current Company = $5,
Company A = $6.29 and
Company B = $6.71.
The highest productivity in terms of revenue per dollar of input is provided by Company B.
