Acme Corp. makes couches and chairs using three main components: wood, foam, and
fabric. It takes 60 linear feet to make a couch and 35 to make a chair. It takes 30 hours
of labor to make a couch and 15 to make a chair. Couches sell for $800 and chairs for
$350.
The selling price would be part of which element?

State the mathematical representation to show that the total number of linear feet of
wood for both couches (X) and chairs (Y) cannot exceed 5,000.
a. 60X + 35Y >= 5,00060X + 35Y >= 5,000
b. 35X + 60Y = 5,00035X + 60Y = 5,000
c. 60X + 35Y <= 5,00060X + 35Y <= 5,000 - Answers - This adds 60 linear feet for each
couch made to 35 linear feet for each chair made to arrive at total linear feet that cannot
be exceeded
c. 60X + 35Y <= 5,00060X + 35Y <= 5,000

, State the mathematical representation to show that the company must make at least 20
chairs to fill backorders.
Y = 20
Y >= 20Y
Y <= 20 - Answers - = is not appropriate
< is making less than required
Therefore the correct answer is:
Y >= 20Y

b. Define the problem.
c. Establish the constraints. - Answers - b. Define the problem.
Which of the following is the term used for the outcome decision to be made that is
governed by the constraints?
Bounded region
Objective function
Center point - Answers - Objective function
The cells listed in the By Changing Cells in the Solver window are referring to which of
the following?
Constraints
Decision variables
Objective function - Answers - Decision variables
Which of the following inventory costs would be a carrying cost?
a. Utilities for the warehouse.
b. Sending in a purchase order.
c. Inspecting incoming inventory. - Answers - a. Utilities for the warehouse.
What is a benefit of using EOQ?
a. It is based on a probability coefficient.
b. It considers all inventory factors in the calculations.
c. It can minimize storage space used. - Answers - c. It can minimize storage space
used.
