The following table lists the components needed to assemble an end item. Assume there is no on-hand inventories.

Item Direct Components End item L(1), C(1), K(1) L B(2), J(3) C G(2), B(2) K B(2) B J G

Item	Direct components
end item	L(1), C(1), K(1)
L	B(2), J(3)
C	G(2), B(2)
K	B(2)
B
J
G

If 30 units of the end item are to be assembled, how many units of component B are needed? Input should be an exact number.
