1.To draw the demand curve, the price for using public transportation must be held constant. If the cost of riding the bus declines, which of the following statements are true? The commuter’s demand curve for gasoline may change The ceteris paribus assumption is violated The commuter may ride the bus more and consume less gasoline 2

Acompany manufactures x units of product a and y units of product b, on two machines, i and ii. it has been determined that the company will realize a profit of $3 on each unit of product a and $4 on each unit of product b. to manufacture a unit of product a requires 7 min on machine i and 5 min on machine ii. to manufacture a unit of product b requires 8 min on mchine i and 5 min on machine ii. there are 175 min available on machine i and 125 min available on machine ii in each work shift. how many units of a product should be produced in each shift to maximize the company's profit p?

Aproduct has a demand of 4000 units per year. ordering cost is $20, and holding cost is $4 per unit per year. the cost-minimizing solution for this product is to order: ? a. 200 units per order. b. all 4000 units at one time. c. every 20 days. d. 10 times per year. e. none of the above

In a transportation minimization problem, the negative improvement index associated with a cell indicates that reallocating units to that cell would lower costs.truefalse
