can you please help me with this 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 no one ???? heelooo
