Consider the following five utility functions.

G(x,y) = (x)^1/2 + y

H(x,y) = (x+1)^1/2 + y + 1

L(x,y) = ln(x) + y

U(x,y) = x e^y

W(x,y) = 100 x - 4x² + 3 y

Z(x,y) = -(100 - x)² -3 (y-200)²

a.G

b.U

c.None.

d.W

e.Z

f.L

In your own words, explain what chemically happens in Equation 1 and Equation 2.

Equation 1: M^2+ (aq) +In^2- (aq) --> MIn(aq)

Where M is colorless, In is blue, and MIn is pink

Equation 2: MIn (aq) + EDTA^4- (aq) --> M(EDTA)^2- (aq) + In^2- (aq)

Where MIn is pink and In is blue

The company bought debentures with a face value of $1 45 ,000 and paid $1 2 5 ,000 to the issuer plus a purchase commission of $2 ,000 . The debentures have a life of 4 years and will pay a coupon of 6.53 % per year at the end of each year. These instruments have been classified as subsequently measured at fair value th rough profit and loss . By the end of the 4 th year, Australian interest rates have moved to 1 2 %. The fair value amounts for this debenture at the end of each year are : Year Fair Value 1 $133,000 2 $147,000 3 $123,000 4 $ 154,469 Required : a. Calculate the effective rate of return (the market rate of interest) for these debentures . ( 3 marks ) b. Prepare a table which shows the movements relating to these debentures over their life . Please remember, these debentures are not held at amortized cost. ( 5 marks ) c. Prepare journal entries for all transactions relating to these debentures . ( 12 marks )

Four sectors of the U.S. economy are (1) livestock and livestock products, (2) other agricultural products, (3) forestry and fishery products, and (4) agricultural, forestry, and fishery services. Suppose that in 1977 the input-output table involving these four sectors was as follows (all figures are in millions of dollars).

Determine how these four sectors would react to an increase in demand for livestock (Sector 1) of $1,000 million, how they would react to an increase in demand for other agricultural products (Sector 2) of $1,000 million, and so on. (Round your answers to two decimal places. Let the columns of the matrix be given in millions of dollars.)

Answer is a 4x4 Matrix and is NOT 0.182 or 0.878 for the first box in the matrix answer

1. Pringles is entering a new market. They are trying to decide which of 100 different (real) flavors to produce to maximize profits. The profit margin for each flavor is listed in pringles.xlsx, as well as the seconds needed per can for 3 different production processes: Flavoring, Packaging, and Quality Check.

The local Pringles factory can devote 100 hours to Flavoring, 120 hours to Packaging, and 80 hours to Quality Checking. Management wants to supply a variety of Pringles to draw in more customers, so they’ve decided to limit production of any single flavor to 5000 cans.

What should Pringles produce for the new market?
