6. Tucker, Inc., produces high-quality suits and sport coats for men. Each suit requires
1.2 hours of cutting time and 0.7 hours of sewing time, uses 6 yards of material, and pro-
vides a profit contribution of $190. Each sport coat requires 0.8 hours of cutting time and
0.6 hours of sewing time, uses 4 yards of material, and provides a profit contribution of
$150. For the coming week, 200 hours of cutting time, 180 hours of sewing time, and
1200 yards of fabric are available. Additional cutting and sewing time can be obtained
by scheduling overtime for these operations. Each hour of overtime for the cutting opera-
tion increases the hourly cost by $15, and each hour of overtime for the sewing operation
increases the hourly cost by $10. A maximum of 100 hours of overtime can be scheduled.
Marketing requirements specify a minimum production of 100 suits and 75 sport coats. Let
S = number of suits produced
number of sport coats produced
DI = hours of overtime for the cutting operation
%3D
SC
%3D
D2 = hours of overtime for the sewing operation

The computer solution is shown in Figure 3.19.
a. What is the optimal solution, and what is the total profit? What is the plan for the use
of overtime?
