 Suppose the market for kittens adoption centre can be described by the following equations:
Demand equation: Q_{d} = 100 – 20P
Supply equation: Q_{s} = 130 + 2P
Calculate the equilibrium price (P) and quantity (Q) of kittens. Remember that a negative price of kittens is not allowed. How many kittens will be adopted by humans and how many will be “strays?”

 Economists have made estimates of the price elasticity of demand for a variety of goods and services. They have also estimated income elasticity and crossprice elasticity.

 Seiko is planning to increase the price of its watches by 10 percent in the coming year. Economic forecasters expect real disposable personal income to increase by 6 percent during the same period. From past experience, the price elasticity of demand has been estimated to be approximately 1.3 and the income elasticity has been estimated at 2.0. These elasticities are assumed to remain constant over the range of price and income changes anticipated. Seiko currently sells 2 million watches per year. Determine the forecasted demand for next year (assuming that the percentage price and income effects are independent and additive).

 Plot the (i) total product, (ii) marginal product, and (iii) average product functions. (Note: Some relationships on the following graph may not appear exactly correct because the graph plots discrete, not continuous values. With smaller discrete intervals these problems disappear. You may want to try this.)
