9. Suppose that a company's output is given by the Cobb-Douglas production function , where L and K are the numbers of units of labor and capital that are used. To stay within its budget of \$2520, these amounts must satisfy 35L +140K = 2520 . Find the amounts of labor and capital that maximize production subject to the budget constraint.

10. The 72 rule says that money invested at 6% per year doubles in approximately 12 years. Also, money invested at 8 % per ycar doubles in approximately 9 years. Suppose that the number of years n is required for an investment at interest rate r to double in valuc, and i is the interest rate percentage (that is, i =100r). Using In2 = 0.693 and the approximation valid for small , show that it holds .
