A finance company receives $1,000$ loan applications per $30$

day working month and makes accept$/$reject decisions based

upon a thorough review. On average, $20\%$ of all applications

receive approval. An internal audit revealed that the

company has $500$ applications in process at various stages.

In response to customer complaints, the company forms an

initial review team to pre$-$process all applications. Each

application will be categorized either A $($excellent$),$ B $($needs

more detailed review$),$ or C $($reject$).$ On average $25\%$ of the

applications are type A$,25\%$ are type B$,$ and $50\%$ are type C$.$

$70\%$ of type A and $10\%$ of type B applications are approved on

review. Internal audit checks show that $200$ applications are

with the initial review team, $25$ with the type A team, and $150$

with the type B team.
