Either type up and save or write up and scan your answers to a file calledExplanation / Answer
Answer 1:- ? = 5000, L = 2500
W = L / ? = 2500 / 5000 = 0.5 weeks so answer is 0.5 weeks
We care because meat has a limited shelf life.
Answer 2:- ? = 1800/day, and 1800/15 = 120/hr. = 2/min.
W = L / ? = 96 / 2 = 48 min.
So the answer is 48 minutes.
If we look at the time , it seems to be quite long for a restaurant.
Answer 3:- ? = 12,000/yr.
W = 5 weeks = 5/50 = 0.1 years
L = ?W = 12,000(0.1) = 1200 units
Answer 4:- ? = $300 mil./yr.
L = $60 mil.
W = L/? = 60/300 = 0.2 yrs.
.2(12) = 2.4 months
No, this time is not reasonable.
