A maintenance manager has implemented a system for managing the inventory of bulk oil that they use in equipment maintenance, wherebyevery second Monday they check the amount of oil on hand and order more; the replenishment order will then arrive one week later. They have determined that weekly demand averages 300 litres, with a standard deviation of 75 litres. Each litre costs $2.25; the manager wishes to be 97% sure that they dont stock out in a given order cycle. If there are 100 litres on hand on a given Monday in which they are to place an order, how many litres should they order?

	a.	565
	b.	732
	c.	875
	d.	1,032
	e.	1,045
