The truck can carry 400 units of the products, in any combination. Management has set a 97.25% fill rate target for each product.

Product	Di	Yi	xL+R	L+R

2	2,000	83	167	50
3	560	23	46	10
4	850	35	70	20
5	4,200	175	350	120
6	1,000	42	83	32

At a given review instant, assume that the inventory positions of the products are 50, 175, 30, 60, 350, and 100, respectively. Should an order be placed, and if so, how much should be ordered of each product?
