,The production planner for Fine Coffees, Inc. produces two coffee blends: American (A) and
British (B). He can only get 300 pounds of Colombian beans per week and 200 pounds of
Dominican beans per week. Each pound of American blend coffee requires 12 ounces of
Colombian beans and 4 ounces of Dominican beans, while a pound of British blend coffee
uses 8 ounces of each type of bean. Profits for the American blend are $2.00 per pound, and
profits for the British blend are $1.00 per pound. The goal of Fine Coffees, Inc. is to
maximize profits.What is the constraint for Dominican beans? - CORRECT ANSWER✔✔-
4A + 8B ≤ 3,200.
Explanation: Since each pound of A uses 12 ounces of Dominican beans and each pound of B
uses 8 ounces of Dominican beans, it is convenient to convert the supply of Dominican beans
to ounces (200 pounds = 3,200 ounces). Then the constraint should reflect that the usages (4
ounces per pound of A, 8 ounces per pound of B) must be less than the supply.

What is the constraint for Colombian beans? - CORRECT ANSWER✔✔- 12A + 8B ≤ 4,800.
Explanation: Since each pound of A uses 12 ounces of Colombian beans and each pound of B
uses 8 ounces of Colombian beans, it is convenient to convert the supply of Columbian beans
to ounces (300 pounds = 4,800 ounces). Then the constraint should reflect that the usages (12
ounces per pound of A, 8 ounces per pound of B) must be less than the supply.

What is the objective function? - CORRECT ANSWER✔✔- P = 2A + B.
, True or False : A linear programming problem may return fractional solutions (e.g. 4 1/3) for
a resource allocation problem. - CORRECT ANSWER✔✔- True
True or False : Linear programming does not permit fractional solutions. - CORRECT
ANSWER✔✔- False
True or False : For cost-benefit-tradeoff problems, minimum acceptable levels for each kind
of benefit are prescribed and the objective is to achieve all these benefits with minimum cost.
- CORRECT ANSWER✔✔- True
A freelance writer must choose how to spend her time working on several different types of
projects.
Newspaper stories take 3 hours to write and pay a flat rate of $45 per story. Magazine articles
take much longer to write (25 hours) but pay significantly better ($400 per article).
Proofreading is often tedious, but the writer can always find proofreading jobs that pay $20
per hour. The writer wants to maximize her income, but doesn't want to work more than 45
hours per week. Additionally, she dislikes proofreading so she would like to spend no more
than 7 hours per week on that task. Both newspaper stories and magazine articles must be
completed in the week they are started (HINT: use an integer constraint to be sure that all
newspaper and magazine jobs are finished within a week).
