(Weighted average cost of capital) Crawford Enterprises is a publicly held company located in Arnold, Kansas. The firm began as a small tool and die shop but grew over its 35-year life to become a leading supplier of metal fabrication equipment used in the farm tractor industry. At the close of 2015, the firm's balance sheet appeared as follows:

Cash	$420,000
Accounts receivable	$4,760,000
Inventories	$7,700,000	Long-term debt	$11,580,000
Net property, plant, & equipment	$17,811,000	Common equity	$19,111,000
Total assets	$30,691,000	Total debt & equity	$30,691,000

At present the firm's common stock is selling for a price equal to its book value, and the firm's bonds are selling at par. Crawford's managers estimate that the market requires a return of 19 percent on its common stock, the firm's bonds command a yield to maturity of 8 percent, and the firm faces a tax rate of 37 percent.

a. What is Crawford's weighted average cost of capital?

b. If Crawford's stock price were to rise such that it sold at 1.5 times book value, causing the cost of equity to fall to 17 percent, what would the firm's cost of capital be (assuming the cost of debt and tax rate do not change)?
