Answer the questions below using the following information on a firm:

1. What is average total cost at Q=7?

2. What is marginal cost at Q =7?

3. Is this firm operating under increasing or diminishing returns at Q=7? Why?

4. Say this firm is a perfect competitor. If the market price for its product is $ 60, at what output level will it produce at (to maximize profits)?

5. Say this firm is a profit-maximizing monopolist. If the firm is maximizing profit where marginal revenue equals $40, at what output level will this firm be producing?

A dietary supplement capsule weighing 4.84 g was ground into a fine powder. Two portions of the solid, both weighing 0.137 g, were dissolved in dilute acid and transferred to 50 ml volumetric flasks. To one of these, 5 ml of 40 ppm Mn2+ was added, and then both flasks were diluted to the mark with distilled water. When aspirated into the flame of an atomic absorption spectrometer set at a manganese absorption wavelength, the absorbances of the unknown and unknown plus standard were 0.374 and 0.641, respectively. Calculate the percentage of Mn in the capsule.

Calculation of individual costs and WACC: Dillon Labs has asked its financial manager to measure the cost of each specific type of capital as well as the weighted average cost of capital. The weighted average cost is to be measured by using the following? weights: 40?% long-term debt, 15?%

preferred? stock, and 45?% common stock equity? (retained earnings, new common? stock, or? both). The?firm's tax rate is 40?%.

Debt: The firm can sell for $950 a 11?-year, $1,000?-par-value bond paying annual interest at a 12.00?%

coupon rate. A flotation cost of 2.5?% of the par value is required in addition to the discount of $50 per bond.

Preferred stock: 8.00?% (annual dividend) preferred stock having a par value of $100 can be sold for $80.

An additional fee of $22 per share must be paid to the underwriters.

Common stock: The? firm's common stock is currently selling for $70 per share. The dividend expected to be paid at the end of the coming year? (2016) is $3.68. Its dividend? payments, which have been approximately 50?% of earnings per share in the past 5? years, were as shown in the following? table:

It is expected that to attract? buyers, new common stock must be underpriced $44 per? share, and the firm must also pay $2.50 per share in flotation costs. Dividend payments are expected to continue at 50?% of earnings. ?

(Assume that rr? = rs?)   [Round to two decimal places]

a.??Calculate the? after-tax cost of debt.

b.??Calculate the cost of preferred stock.

c.??Calculate the cost of common stock.

d.??Calculate the WACC for Dillon Labs.

QUESTION 5

If the flow hydrograph as listed in the Table Q5 passes through a stream reach from A to B, for which K = 8.0 hr and x = 0.3

1. Determine the peak outflow discharge at B. At t=0, the outflow discharge is 40 m³/s
2. Based on the inflow and outflow hydrograph, discuss the time lag required for the peak flood to reach the downstream area. Comment on the attenuation achieved.

short answers:

A. In the short run, how does a business manager make wise use of the relationship between the marginal product, the average product, and the total product to help determine the point at which maximum output efficiency is achieved?

B. Analyze each action below one at a time and explain if it is a short run action or a long run action, and explain why.

Shi Import-Export's balance sheet shows $300 million in debt, $50 million in preferred stock, and $250 million in total common equity. Shi's tax rate is 40%, r_d = 7%, r_ps = 8.1%, and r_s = 11%. If Shi has a target capital structure of 30% debt, 5% preferred stock, and 65% common stock, what is its WACC? Round your answer to two decimal places.

Hector Gonzales runs the floral art company, which supplies floral arrangements to three large supermarket chains throughout Australia. Management has become concerned about the rising costs associated with the process and dispatch of orders. An activity analysis of the indirect costs identified the following customer related cost.

                                                                                                       Use of cost drivers

                                                                                                                Supermarket customers

1. Assign the activity costs to ach of the three customers
2. Calculate the contribution for each customer if the sales pattern for each as follows:

Supermarket customer            Sales revenue**

1. $350,000
2. S160,000
3. $210,000

**Selling price is marked up 50% on direct cost of flowers

Hints: conduct a customer profitability analysis based on the above customer related indirect costs.

3. What conclusion can we draw from the customer profit analysis? Advise the management of the Floral Art Company as to whether any changes should be made in its relationships with customers. Advise Hector as to how he should go about executing these changes.

One unit of A is made of three units of B, one unit of C, and two units of D. B is composed of two units of E and one unit of D. C is made of one unit of B and two units of E. E is made of one unit of F.

     Items B, C, E, and F have one-week lead times; A and D have lead times of two weeks.

     Assume that lot-for-lot (L4L) lot sizing is used for Items A, B, and F; lots of size 65, 65, and 180 are used for Items C, D, and E, respectively. Items C, E, and F have on-hand (beginning) inventories of 12, 80, and 150, respectively; all other items have zero beginning inventory. We are scheduled to receive 9 units of A in Week 2, 50 units of E in Week 1, and also 50 units of F in Week 1. There are no other scheduled receipts. If 35 units of A are required in Week 8, use the low-level-coded bill of materials to find the necessary planned order releases for all components.

Develop an MRP planning schedule showing gross and net requirements and order release and order receipt dates. (Leave no cells blank - be certain to enter "0" wherever required.)
