Let X1: number of hardback books produced
Let X2: number of paperback books produced
Let 1 shift = 8 hours = 480 minutes
Objective function:
Maximize Z = 10 X1 + 6 X2
Subject to:
1/4 X1 + 1/8 X2 <= 480 [cover department capacity]
1/6 X1 + 1/4 X2 <= 480 [printing department capacity]
1/3.5 X1 <= 480 [framing department capacity]

Answer to supplemental problem 2
Let X1: number of pounds of B22 Binder
Let X2: number of pounds of T90 Zinc Oxide
Let X3: number of pounds of P55 Petroite
Objective function:
Minimize C = 0.3 X1 + 0.2 X2 + 0.4 X3
Subject to:
X1/X3 <= 4 [ratio of B22:P55]
X2 <= 60000 [T90 availability]
X1 + X2 + X3 = 400000 [resin requirement]
X1, X2, X3 = 0 [non-negativity]
Answer to Supplemental Problem 3
Let X1: acres of Milo planted
Let X2: acres of Soybean planted
Objective function:
Maximize Profit = 500 X1 + 700 X2
Subject to:
X2 <= 100 [acreage limit for Soybean]
2000 X1 + 1000 X2 <= 200000 [fertilizer availability]
X1, X2 >= 0 [non-negativity]
