Manufacco company produces part #2206 for the aerospace industry. Each unit of part #2206 is sold for SR15. The unit production cost of part #2206 is SR3. The fixed monthly cost of operating the production facility is SR3000. How many units of part #2206 have to be sold in a month to break even?

a) 166.67

b) 200

c) 250

d) 500

 

 

 

5) A BBCo, a bed-and-breakfast company breaks even every month if their customers book 300 rooms over the course of a month. Their fixed cost is SR6000 per month and the revenue they receive from each booked room is SR180. What is their variable cost per occupied room?

a) SR130

b) SR140

c) SR148

d) SR160

 

A baker uses organic flour from a local farmer in all of his baked goods. For each batch of bread (x1), he uses 4 pounds of flour. For a batch of cookies (x2), he uses 3 pounds, and for a batch of muffins (x3) he uses 2 pounds. The local farmer can supply him with no more than 24 pounds per week. The constraint that represents this condition is: a) x1 ≤ 8, x2 ≤ 8, x3 ≤ 8

b) x1 + x2 + x3 ≥ 24

c) x1 + x2 + x3 ≤ 24

d) 4x1 + 3x2 + 2x3 ≤ 24

 

 

Mohammad's Fish Market buys salmon (S) for SR5 per pound and a local whitefish (W) for SR3.50 per pound. Mohammad wants to minimize his cost, but he cannot spend more than SR160. The objective function that minimizes these costs for Mohammad is: a) 5S + 3.5W ≤ 160

b) Min 5S + 3.5 W

c) Max 5S + 3.5 W

d) Min 5S + 3.5W ≥ 160

 

Jeddah University is planning a seminar. It costs SR3000 to reserve a room, hire an instructor, and bring in the equipment. Assume it costs SR25 per student for the administrators to provide the course materials. If we know that 20 people will attend, what price should be charged per person to break even? a) SR120

b) SR150

c) SR175

d) SR200

 

In a linear programming problem, a valid objective function can be represented as: a) Max Z = 5xy

b) Max Z 5x2 + 2y2

c) Max 3x + 3y + 1/3 z

d) Min (x1 + x2) / x3

 

11) Which of the following could not be a linear programming problem constraint? a) 1A + 2B ≠ 3

b) 1A + 2B = 3

c) 1A + 2B ≤ 3

d) 1A + 2B ≥ 3

heelooo

I find the way in which this was asked quite arrogant.

 

First of all, no own contribution about what already has been attempted by OP himself to solve the problem ... "no one ???? heelooo", seriously?

 

I always try to teach people something when they post something in the homework help section. But I don't feel the need to help you specifically with your problems, that is, the problems you identify as your problems.

 

Let this be a lesson for decrementing your arrogance (which probably wasn't meant as such, but can be interpreted as such)

I'll help you with these two but I won't give you the answers, you'll have to work them out for yourself. The first problem is essentially asking how many units sold for SR15 apiece will equal the cost of SR3000? Your solution involves division.

 

Your second problem involve multiplication, subtraction, and finally division. To get the breakeven cost per month you will have to multiply the number of rooms booked by the SR received for each booking. This will give you the total breakeven cost, which includes fixed cost. Next, you will have to subtract the fixed cost provided (SR6000) from the total breakeven cost and then divide your answer by the original number of rooms booked to get the variable cost per room.

 

These all appear to be fairly simple problems to solve on you own with very little effort. Good Luck!
