Make 0.3M from 1M stocks. Each measurement will require 3 ml of solution in a glass test tube

a) Glucose, 0.3 M

b) Ethanol, 0.3 M (Density = 0.789g/ml and 46.1g/mol)

c) Methanol, 0.3M (0.71g/ml and 34g/mol)

d) Isopropyl alcohol 70% (0.79g/ml and 60.1 g/mol)

1. Following are the returns on two assets and three states of the economy

1. What are the expected returns and standard deviations for these two stocks?

1. The Public Good Problem A national park that costs MC = 80 dollars to provide to society has been privatized and handed over to a private firm; the firm is mandated to price at marginal cost. There are two types of consumers, a group of high demand consumers (group A) that have an aggregate demand function equal to MB = 100 – Q, and a low demand group of consumers (group B) with aggregate demand equal to MB = 50 – Q, where Q is thousands of acres.

A. How many acres will be provided by the firm when pricing at MC, assuming that the low-demand group will free-ride on the high-demand group?

B. What is the aggregate demand curve for the national park? (Hint: the aggregate demand curve for a public good is the vertical aggregation of the individual demand curves.)

C. Calculate the aggregate consumer surplus for the two types of consumers when the firm prices at MC. (Hint: in this case, the group B is free riding, and they can gain extra consumer surplus)

D. If the national park is provided by the government, how many acres SHOULD be provided?

Springfield Acting Co. is a professional actor training group that trains stage actors and is headquartered in Los Angeles. The CEO of the company, Milhouse Van Houton, is considering expanding and opening an office in New York City but he just received an interesting business opportunity in the San Francisco area to partner with a movie production company located there. Milhouse knows he can only accept one of these opportunities at the current time. He has already purchased his non-refundable ticket to New York, but his hotel reservation is still cancelable. The cost of each trip is outlined below.

Required:

1. What are the relevant costs of each trip?
2. What is the incremental cost?
3. Without considering qualitative factors (thus use numbers to analyze), which alternative should Milhouse choose? Why?
4. What are two qualitative factors that Milhouse might consider?

Park Corporation is planning to issue bonds with a face value of $2,400,000 and a coupon rate of 9 percent. The bonds mature in 10 years and pay interest semiannually every June 30 and December 31. All of the bonds were sold on January 1 of this year. Park uses the effective-interest amortization method and also uses a premium account. Assume an annual market rate of interest of 7.5 percent. (FV of $1, PV of $1, FVA of $1, and PVA of $1) (Use the appropriate factor(s) from the tables provided.)

Required:

1. Prepare the journal entry to record the issuance of the bonds. (If no entry is required for a transaction/event, select "No journal entry required" in the first account field.)

   
    
2. Prepare the journal entry to record the interest payment on June 30 of this year. (If no entry is required for a transaction/event, select "No journal entry required" in the first account field. Round your final answer to whole dollars.)

3. How will Park present its bonds on its June 30 balance sheet? (Round your final answer to whole dollars.)
