Assume that the manufacturing of cellular phones is a perfectly competitive indus-try. The market demand for cellular phones is described by a linear demand function:QD=6000−50P9. There are fifty manufacturers of cellular phones. Each manufacturerhas the same production costs. These are described by long-run total and marginal costfunctions ofTC(q)=100+q2+10q,andMC(q)=2q+10.a. Show that a firm in this industry maximizes profit by producingq=P−102.b. Derive the industry supply curve and show that it isQS=25P−250.c. Find the market price and aggregate quantity traded in equilibrium.d. How much output does each firm produce? Show that each firm

The mean cost of domestic airfares in the United States rose to an all-time high of $375 per ticket. Airfares were based on the total ticket value, which consisted of the price charged by the airlines plus any additional taxes and fees. Assume domestic airfares are normally distributed with a standard deviation of $100. Use Table 1 in Appendix B. a. What is the probability that a domestic airfare is $550 or more (to 4 decimals)? b. What is the probability that a domestic airfare is $265 or less (to 4 decimals)? c. What if the probability that a domestic airfare is between $310 and $480 (to 4 decimals)? d. What is the cost for the 3% highest domestic airfares? (rounded to nearest dollar)

Sheffield Inc. had beginning inventory of $25,200 at cost and $42,000 at retail. Net purchases were $252,000 at cost and $357,000 at retail. Net markups were $21,000, net markdowns were $14,700, and sales revenue was $308,700. Assume the price level increased from 100 at the beginning of the year to 115 at year-end. Compute ending inventory at cost using the dollar-value LIFO retail method. (Round ratios for computational purposes to 1 decimal place, e.g. 78.7% and final answer to 0 decimal places, e.g. 28,987.)

Ending inventory using the dollar-value LIFO retail method $_________

You are trying to get the cheapest airfare to reach your hometown. You just found on makemytrip.com that the ticket home will cost $400, and it cannot be refunded or exchanged. You also have the option of buying a ticket for $450, which can be refunded for $350 (and thus costs you $100). The price of tickets is expected to change in one week, and you will have one more chance to buy a ticket. There is a 50% chance that the ticket would cost $300, and a 50% chance that it would cost $600. Construct a decision tree and determine the best course of action to minimize the expected expense. Assume that you (decision maker) are a sensible adult who takes rational decisions!!

You are considering how to invest part of your retirement savings.You have decided to put $ 100 comma 000 into three​ stocks: 53 % of the money in GoldFinger​ (currently $ 20​/share), 18 % of the money in Moosehead​ (currently $ 70​/share), and the remainder in Venture Associates​ (currently $ 10​/share). Suppose GoldFinger stock goes up to $ 43​/share, Moosehead stock drops to $ 68​/share, and Venture Associates stock drops to $ 9 per share.

a. What is the new value of the​ portfolio?

b. What return did the portfolio​ earn?

c. If you​ don't buy or sell any shares after the price​ change, what are your new portfolio​ weights?

ABC firm is selling bonds for​ $950 a bond with​ $1,000 par value at​ 5% coupon paid annually. The bond will mature in 8 years. Firm is selling​ 10,000 such bonds. This firm is also selling preferred stock at​ $75 per share. Firm is selling​ 100,000 such shares at​ 8% dividend with​ $100 par value. This firm is also raising money by selling another issue of common stocks. The most recent dividend was​ $4.50 and this firm is expecting to grow at​ 7% rate per year forever. The current selling price of their stock is​ $60 and company is planning to sell​ 300,000 shares. Estimate Weighted Average Cost of Capital​ (WACC). This firm is in​ 40% tax bracket.

Suppose there are two firms in an instant coffee market. Market demand curve is given by P = 100 – 2Q, and marginal cost of production for both firms are equal and constant at m=12.

a) Find the output that will maximize firm’s profit if two firms choose quantity simultaneously. What is the price that they will charge and how much is the profit of each firm?

b) Suppose the quantity game as in (b) is played by the firm over and over multiple times. Compute the revenue matrix for these firms where two actions are possible taken by the firm is either cooperative or non-cooperative. Based on the resulting matrix, calculate the possible discount factor value the two firms continue to work together.

The mean cost of domestic airfares in the United States rose to an all-time high of $380 per ticket. Airfares were based on the total ticket value, which consisted of the price charged by the airlines plus any additional taxes and fees. Assume domestic airfares are normally distributed with a standard deviation of $100. Use Table 1 in Appendix B.

a. What is the probability that a domestic airfare is $545 or more (to 4 decimals)?

b. What is the probability that a domestic airfare is $255 or less (to 4 decimals)?

c. What if the probability that a domestic airfare is between $320 and $490 (to 4 decimals)?

d. What is the cost for the 5% highest domestic airfares? (rounded to nearest dollar)

A generator at a utility company produces 100 A of current at 4.0 x 103 V. The voltage is stepped up to 2.4 x 105 V by a transformer before being sent on a high voltage line across a rural area to a city. Assume the effective resistance of the line is 30.0 Ω and the transformers are ideal.

a. Determine the percentage of power lost in the transmission line.

b. What percentage would be lost if the voltage would not have been stepped up?

c. How many kW-hr of energy is lost each day if the voltage would not have been stepped up?

d. Calculate the cost of this energy loss if the price of electricity is $.11/kW-hr.

Design the logic in pseudocode for Bugz App software company that sells a software package
as follows.
1. The retail price of the package is $99
2. Quantity discounts are given on purchases of 10 or more units as follows The program
must allow the user to enter the customer’s name and number of units purchased, and
output the original cost of the units purchased, the percentage discount given, the dollar
amount of the discount given, and the final cost after discount.
1. If the customer purchases up to 19 units, they receive a discount of 20%
2. 20 to 49 units – discount of 30%
3. 50 to 99 units – discount of 40%
4. 100 or more units – discount of 50%
