Suppose a firm has the following demand equation:
where Q = quantity demanded
P = product price (in dollars)
Q=1,000 3,000P + 10A
A = advertising expenditure (in dollars)
Assume for the following questions that P =3$ and A = $2,000.
1. Suppose the firm dropped the price to $2.50. Would this be beneficial? Explain. Illustrate
your answer with the use of a demand schedule and demand curve.
2. Suppose the firm raised the price to $4.00 while increasing its advertising expenditure by $100.
Would this be beneficial? Explain. Illustrate your answer with the use of a demand schedule
and a demand curve. (Hint: First construct the schedule and the curve assuming A = $2,000.
Then construct the new schedule and curve assuming A = $2,100.)
ABC Sports, a store that sells various types of sports clothing and other sports items, is planning
to introduce a new design of Arizona Diamondbacks' baseball caps. A consultant has estimated the
demand curve to be
where Q is cap sales and P is price.
Q=2,000 100P
1. How many caps could ABC sell at $6 each?
2. How much would the price have to be to sell 1,800 caps?
3. Suppose ABC were to use the caps as a promotion. How many caps could ABC give away
free?
4. At what price would no caps be sold?
5. Calculate the point price elasticity of demand at a price of $6.

- A village has six residents, each of whom has accumulated savings of $100. Each villager can use this money either to buy a government bond that pays 18 percent interest per year or to buy a year-old llama, send it onto the commons to graze, and sell it after 1 year. The price the villager gets for the 2-year-old llama depends on the quality of the fleece It grows while grazing on the commons. That in turn depends on the animal's access to grazing, which depends on the number of llamas sent to the commons, as shown in the following table: Number of 11amas on the commons Price per 2- year-old 11ama ($) 1 125 2 119 3 116 4 113 5 6 111 109 The villagers make their investment decisions one after another, and their decisions are public. a.
