The Anderson Corporation (an all-equity-financed firm) has a sales level of $300,000 with a 12 percent profit margin before interest and taxes. To generate this sales volume, the firm maintains a fixed-asset investment of $150,000. Currently, the firm maintains $50,000 in current assets.

a) Determine the total asset turnover for the firm and compute the rate of return on total assets before taxes.

B) Compute the before-tax rate of return on assets at different levels of current assets starting with $10,000 and increasing in $15,000 increments to $100,000.

C) If the new current assets were financed with long-term debt at 15 percent interest, what would be the before-tax interest cost if the new current assets added equals $40,000?
