should be \10 of total sales, and the federal-plus-state tax rate is \40. a. What is the expected return on equity under each current assets level? Round your answers to two decimal places. Restricted policy \ Moderate policy \ Relaxed policy \ b. In this problem, we assume that expected sales are independent of the current assets investment policy. Is this a valid assumption? I.

A firm's current asset policies may have a significant effect on sales. IV. Yes, this assumption would probably be valid in a real world situation. A firm's current asset policies have no significant effect on sales. V. Yes, sales are controlled only by the degree of marketing effort the firm uses, irrespective of the current asset policies it employs. c.
