50) In pricing her line of Smart Phone Cases, Lucie Loo remembers hearing that she needs to consider three decisions with respect to pricing her product line. She seems to remember that one decision is to identify the lowest-priced product and set the price to drive traffic. Another decision she needs to make is to identify the highest priced product and position it as her premium offering. What is the third decision Lucie needs to make?

estimate the total Economic Value (EV) for the complete product line to ensure she makes a profit

set the price differentials for all other products in the line to reflect their perceived value

ensure that the cross elasticity of demand between the products is positive

set the prices for the rest of the line to minimize product cannibalization

determine the break-even quantity for each item so that she knows how much inventory to have on hand for each item

A company's management is considering to buying a new machine. A new machine will cost $25,000. Annual operating and maintenance costs will be $8,000 in the first year, increasing by $400 each year. Assume the machine depreciates by $4,000 per year according to straight-line depreciation. Assume the machine can be re-sold at its book value at any time.

a) Owning the proposed new machine for how many years will result in the minimum EAC if the interest rate is 8%? (show steps)

b) If the old machine reached its minimum EAC several years ago and its operating and maintenance cost this year are expected to be $9,000, should the arena’s management buy the new machine? Assume the operating and maintenance costs of the old machine will increase, and assume it has a salvage value of zero.

The demand for Greta’s Grinders can be characterized by the following point elasticities: price elasticity = -0.8, cross-price elasticity with Melvin’s Mashers = -2, and income elasticity = 1.2. Which of the following statements is false?

1. A price increase for Greta Grinders will decrease both the number of units demanded and the total revenue Gail gets.
2. The cross-price elasticity indicates that a 4% increase in the price of Melvin’s Mashers will cause an 8% increase in quantity demanded of Greta Grinders.
3. An 8% price reduction for Greta Grinders would be necessary to overcome the effects of a 4% decline in income.
4. All the above statements are false.  

Suppose market demand and supply are given by Q_d= 400-12P and Q_s= -20 + 8P. If a price floor of $20.00 is imposed,

1. there will be a surplus of 10 units.
2. there will be neither a surplus or shortage.
3. there will be a shortage of 16 units.  
4. None of the above choices makes any sense in this case.

Jack and Jill are in the checkout line at Walmart. In Jack’s basket he has 4 DIGIORNO Original Thin Crust Supreme Frozen Pizza and 2 half-gallons of Blue Bell Chocolate Chip Cookie Dough. Jill has in her basket 6 of the DIGIORNO pizzas and 1 half-gallon of the Blue Bell ice cream. You know that the pizza are selling for $5.00 each while ice cream costs $4.00 per half-gallon. If both Jack and Jill are utility maximizers, which of the following statements is incorrect.

1. Jack and Jill have different budgets to spend on pizzas and ice cream.
2. Given what is in his basket, Jack’s marginal utility for pizzas is 1.25 his marginal utility for ice cream.
3. Jill’s marginal rate of substitution between pizzas and ice cream is larger than Jack’s since she has more pizzas than ice cream in her basket compared to the ratio in Jack’s basket.
4. Given what is in her basket, Jill’s marginal utility for ice cream is 0.8 her marginal utility for pizzas.
5. All the above are correct.
