Problem $9-22($Algo$)$

Product A consists of three units of Subassembly B$,$ three units of $C,$ and one unit of $D.$ B is composed of four units of $E$ and three units

of $F.C$ is made of two units of $H$ and two units of $D.H$ is made of five units of $E$ and two units of $G.$

To produce $100$ units of $A,$ determine the numbers of units of $B,C,D,E,F,G,$ and $H$ required using the low$-$level coded product

structure tree.
