A service station orders 100 cases of motor oil every 6 months. The number of cases of oil remianing in?

t months after the order arrives is modeled by:





f(t)=100^-0.5t





(a) How many cases are there at the start of the six month period? How many cases are left at the end of the six month period?





(b) Find the average number of cases in inventory over the six-month period.A service station orders 100 cases of motor oil every 6 months. The number of cases of oil remianing in?
a)1 to start with, 1x10^-60 at the end of the 6 month period.


b) about half a barrel on average.A service station orders 100 cases of motor oil every 6 months. The number of cases of oil remianing in?
More interesting is looking at how much oil is left at the end of *each* month, and therefore how much business they are doing. They're doing a *lot* more business some months than others. (they blast through the first 90 cases in one month, then take 5 months to use the next 9 - what sort of business is *that*? :)
