Suppose a tax is imposed on each new hearing aid that is sold. The supply curve is a typical upward-sloping straight line, and the demand curve is a typical downward-sloping straight line. As a result of the tax, the equilibrium quantity of hearing aids decreases from 10,000 to 9,000, and the deadweight loss of the tax is $60,000. We can conclude that the tax on each hearing aid is a. $60. b. $120. c. $200. d. $160.

The management of a private investment club has a fund of $250,000 earmarked for investment in stocks. to arrive at an acceptable overall level of risk, the stocks that management is considering have been classified into three categories: high risk (x), medium risk (y), and low risk (z). management estimates that high risk stocks will have a rate of return of 15%/year; medium risk stocks, 10%/year; and low risk stocks, 6%/year. the amount of money invested in low risk stocks is to be twice the sum of the amount invested in stocks of the other two categories. if the investment goal is to have a rate of return of 9% on the total investment, determine how much the club should invest in each type of stock. (assume that all the money available for investment is invested.)

The plastic flowerpots company has two manufacturing departments, molding and packaging. at the beginning of the month, the molding department has 2,100 units in inventory, 70% complete as to materials. during the month, the molding department started 18,500 units. at the end of the month, the molding department had 3,150 units in ending inventory, 80% complete as to materials. units completed in the molding department are transferred into the packaging department. cost information for the molding department for the month follows: beginning work in process inventory (direct materials) $ 1,300 direct materials added during the month 28,900 using the weighted-average method, compute the molding department's (a) equivalent units of production for materials and (b) cost per equivalent unit of production for materials for the month. (round "cost per equivalent unit of production" to 2 decimal places.)
