Problem $3$:

Part A is produced on machine $1$ and then machine $2.$ One unit of Part A is assembled

with three units of Part B$,$ which is produced on machine $3,$ in assembly station $4.$

Ma$-$ chine $1$ has a scrap factor of $20\%,$ and machine $2$ has a scrap factor of $10\%.$ The

assembly process has a scrap factor of $15\%.$ Another part, Part C$,$ is produced on

machine $5$ and has a scrap estimate of $25\%.$ Part C and the subassembly comprison

of Part A and Part B are assembled at assembly station $6$ into the completed product.

Each day, $15,000$ units of the completed product are required to meet demand.

Assuming that machine $3$ and assembly station $6$ have scrap factors of $30\%$ each,

what are the requirements for Parts $A,B,$ and C in order to meet the daily demand

for the completed product? $($Answer: $35,014,25,210,$ and $28,571$ units$)$
