Decision Variables:

$B=$# of Basic models to be produced, profit$=$$$45/$unit

$P=$ # of Premium models to be produced, profit $=$$$\frac{120}{?}$ unit

Objective: MaxTotal Profit $=$ Max $$45B+$$$120P$

Constraints:

$\backslash$table$[[$Software Engineer $($SE$)$:$,20B+5P,2400$ minutes$],[$QC Manager:,$15B+30P,2400$ minutes$],[$Demand for B:$,$B$,100$ units$],[$Demand for P:$,$P$,50$ units$]]$

Bottleneck Resource is QC$,$ Preferred product is $P.$ Optimal production: $B=60,P=50,$OFV$=$ $$8700.$

Question: Shadow Price for $"QC"$ is:
