Suppose D(x) = 30 x is the demand price per ounce for a certain product. That is, the typical consumer is willing to pay D(x) dollars per ounce when buying x ounces of the product. The marginal demand is defined as the instantaneous rate of change in demand. In other words, the marginal demand for x ounces of product is equal to D0 (x). If we write MD(x) to denote the marginal demand function, find a formula for MD(x). In other words, calculate D0 (x). Show your work! Note: if the concept of demand and marginal demand is confusing you, then simply focus on finding D0 (x) when D(x) = 30 x . I’m providing this additional context to help you see how the concept of a derivative can be applied in an economic setting

Afirm's before-tax cost of debt, rd, is the interest rate that the firm must pay on debt. because interest is tax deductible, the relevant cost of debt used to calculate a firm's wacc is the cost of debt, rd (1 – t). the cost of debt is used in calculating the wacc because we are interested in maximizing the value of the firm's stock, and the stock price depends on cash flows. it is important to emphasize that the cost of debt is the interest rate on debt, not debt because our primary concern with the cost of capital is its use in capital budgeting decisions. the rate at which the firm has borrowed in the past is because we need to know the cost of capital. for these reasons, the on outstanding debt (which reflects current market conditions) is a better measure of the cost of debt than the . the on the company's -term debt is generally used to calculate the cost of debt because more often than not, the capital is being raised to fund -term projects. quantitative problem: 5 years ago, barton industries issued 25-year noncallable, semiannual bonds with a $1,600 face value and a 8% coupon, semiannual payment ($64 payment every 6 months). the bonds currently sell for $845.87. if the firm's marginal tax rate is 40%, what is the firm's after-tax cost of debt? round your answer to 2 decimal places. do not round intermediate calcu

Question 55 ted, a supervisor for jack's pool supplies, was accused of stealing pool supplies and selling them to friends and relatives at reduced prices. given ted's earlier track record, he was not fired immediately. the authorities decided to give him an administrative leave, without pay, until the investigation was complete. in view of the given information, it would be most appropriate to say that ted was: demoted. discharged. suspended. dismissed.
