What is the maximum profit?

Answer

$25000

$35000

$45000

$55000

$65000

Question 11

The production manager for the Coory soft drink company is considering the production of 2 kinds of soft drinks: regular and diet. Two of her limited resources are production time (8 hours = 480 minutes per day) and syrup (1 of her ingredients) limited to 675 gallons per day. To produce a regular case requires 2 minutes and 5 gallons of syrup, while a diet case needs 4 minutes and 3 gallons of syrup. Profits for regular soft drink are $3.00 per case and profits for diet soft drink are $2.00 per case. For the production combination of 135 cases of regular and 0 cases of diet soft drink, which resources will not be completely used?

Answer

only time

only syrup

time and syrup

neither time nor syrup

Question 12

In a linear programming problem, the binding constraints for the optimal solution are:

5×1 + 3×2 ≤ 30

2×1 + 5×2 ≤ 20

Which of these objective functions will lead to the same optimal solution?

Answer

2×1 + 1×2

7×1 + 8×2

80×1 + 60×2

25×1 + 15×2

Question 13

In a linear programming problem, a valid objective function can be represented as

Answer

Max Z = 5xy

Max Z 5×2 + 2y2

Max 3x + 3y + 1/3z

Min (x1 + x2) / x3

Question 14

Cully furniture buys 2 products for resale: big shelves (B) and medium shelves (M). Each big shelf costs $500 and requires 100 cubic feet of storage space, and each medium shelf costs $300 and requires 90 cubic feet of storage space. The company has $75000 to invest in shelves this week, and the warehouse has 18000 cubic feet available for storage. Profit for each big shelf is $300 and for each medium shelf is $150. What is the objective function?

Answer

MAX Z = $300B + $100 M

MAX Z = $300M + $150 B

MAX Z = $300B + $150 M

MAX Z = $300B + $500 M

Question 17

The production manager for the Coory soft drink company is considering the production of 2 kinds of soft drinks: regular (R) and diet(D). Two of the limited resources are production time (8 hours = 480 minutes per day) and syrup limited to 675 gallons per day. To produce a regular case requires 2 minutes and 5 gallons of syrup, while a diet case needs 4 minutes and 3 gallons of syrup. Profits for regular soft drink are $3.00 per case and profits for diet soft drink are $2.00 per case. What is the time constraint?

Answer

2R + 5D ≤ 480

2D + 4R ≤ 480

2R + 3D ≤ 480

2R + 4D ≤ 480

Question 18

Max z = 3×1 +4×2

s.t. x1 + 2×2 ≤ 16

2×1 + 3×2 ≤ 18

x1 ≥ 2

x2 ≤ 10

x1, x2 ≥ 0

Find the optimal solution. What is the value of the objective function at the optimal solution? Note: The answer will be an integer. Please give your answer as an integer without any decimal point. For example, 25.0 (twenty five) would be written 25

Answer

27

Question 19

Max Z = $3x + $9y

Subject to: 20x + 32y ≤ 1600

4x + 2y ≤ 240

y ≤ 40
