a. Compute the average product cost

I=input=680 orders
%G=percent of good quality product=96%
%R=percent of goods that can be reworked=10%
Yield=Y=I*(%G)+I*(1-%G)*(%R)=680*96%+680*(1-96%)(10%)=655.52

Kd=direct manufacturing cost per unit=$6.15
Kr= rework cost per unit=$1.75
R= reworked units=I*(1-%G)*(%R)=680*(1-96%)*(10%)=2.72
