Exercise 19-5 Absorption costing and variable costing income statements LO P2

Rey Company’s single product sells at a price of $231 per unit. Data for its single product for its first year of operations follow.

1. Prepare an income statement for the year using absorption costing
2. Prepare an income statement for the year using variable costing.

At year-end 2018, Wallace Landscaping’s total assets were $2.09 million, and its accounts payable were $390,000. Sales, which in 2018 were $2.4 million, are expected to increase by 25% in 2019. Total assets and accounts payable are proportional to sales, and that relationship will be maintained. Wallace typically uses no current liabilities other than accounts payable. Common stock amounted to $425,000 in 2018, and retained earnings were $205,000. Wallace has arranged to sell $135,000 of new common stock in 2019 to meet some of its financing needs. The remainder of its financing needs will be met by issuing new long-term debt at the end of 2019. (Because the debt is added at the end of the year, there will be no additional interest expense due to the new debt.) Its net profit margin on sales is 6%, and 35% of earnings will be paid out as dividends. What was Wallace's total long-term debt in 2018? Do not round intermediate calculations. Round your answer to the nearest dollar. $ What were Wallace's total liabilities in 2018? Do not round intermediate calculations. Round your answer to the nearest dollar. $ How much new long-term debt financing will be needed in 2019? (Hint: AFN - New stock = New long-term debt.) Do not round intermediate calculations. Round your answer to the nearest dollar. $

If I deposit $5,000 a year for 10 years, age 25 to 35, at 10% interest, and then let the sum/accumulation sit for 30 years, also earning 10% per year that might be an astute investment. But my older brother who graduated from the “school down south,” says that I should wait until I am 35 and making a ton of money and then I can deposit $7,500 a year for 30 years at 10% and I will be much better off…….since you are a University of Utah grad, and unlike some other universities (Tempe Normal) you can walk and chew gum at the same time, which of the following is correct? Group of answer choices

Both would yield virtually the same sum, within $1,000 of each other without rounding off.

The $5,000 a year would give about $979,258 more because of the power of compound interest.

The $7,500 scenario would provide me with at least $156,786 more.

The $7,500 scenario would provide me with about $156,786 less.

A ball with a mass of 0.605kg is initially at rest. It is struck by a second ball having a mass of 0.430kg , initially moving with a velocity of 0.220m/s toward the right along the x axis. After the collision, the 0.430kg ball has a velocity of 0.215m/s at an angle of 36.0? above the x  axis in the first quadrant. Both balls move on a frictionless, horizontal surface.

What is the magnitude of the velocity of the 0.605kg ball after the collision?

What is the direction of the velocity of the 0.605kg ball after the collision?

What is the change in the total kinetic energy of the two balls as a result of the collision?

Microwaves with a wavelength of 7 cm and sound waves with a wavelength of 7 cm are incident on a

12 cm wide slit. Which of the following is correct?

(a) The diffraction pattern from microwaves and sounds waves is different because the waves have

different velocities.

(b) The frequency of the light is less than that of the sound waves

(c) Both the microwaves and sounds waves have a maximum at about 36 degrees.

(d) Both the microwaves and sounds waves have a minimum at about 36 degrees.

A green laser beam is incident on a pair of narrow slits and an interference pattern is formed on

a distant screen. If the green laser is replaced with a red laser, with everything else the same, the

distance between the fringes will

(a) increase because green light has a longer wavelength than red light.

(b) increase because red light has a longer wavelength than green light.

(c) remain the same because the distance between the slits is doesn’t change.

(d) decrease because green light has a shorter wavelength than the red light.

(e) decrease because red light has a shorter wavelength than the greed light.

Question 2: Application of Basic AD/AS Model to Fiscal Policy. [Suggested writing time: 17 minutes] Suppose due to an impeachment you are the newly elected President of the United States (US). You, with your prudent set of economic advisors, are reviewing the following hypothetical economic data in 2019 to 2020:

Real GDP per capita growth rate = -0.2%

Unemployment rate = 6.8%

Inflation rate = -1.0%

a. Determine what phase of the business cycle the US economy is likely to be experiencing in 2019 to 2020. Provide specific reasons for your answer. b. Use a well-labelled AD/AS diagram to show the position of this economy in 2020. Explain how the US government, using appropriate fiscal policy, might boost the economy back to the long run, full-employment GDP equilibrium. Draw the AD curve shift(s) associated with this policy on your diagram.

Consider a manufacturing process that produces cylindrical component parts for the automotive industry. According to specifications, it is important that the process produces parts having a mean diameter of 5.0 millimeters. An experiment is conducted in which 100 parts produced by the process are selected randomly and the diameter measured on each part. It is known that the population standard deviation is 0.1. It was found that the sample mean diameter is 5.027 millimeters. The process engineer Mr. Tan would like to find out how likely is it that one could obtain a sample mean diameter of at least 5.027 with sample size n = 100, if the population mean µ = 5.0. Apply the concept of central limit theorem. Mr Tan claimed that “In only 7 in 1000 experiments, one would experience by chance a sample mean that deviates from the population mean by as much as 0.027.” Do you agree? Explain your reasoning.

M3 Discussion: The Respiratory System

This is something of a different type of discussion. Discuss in 1-2 short paragraphs 2 of the most informative pieces of information you learned in this chapter. You can discuss one of the homeostatic imbalances, a fundamental principle of respiratory capacities, gas exchange, etc, anything that was presented in the chapter you particuarly are interested in.

Two firms, A and B, sell widgets to a market of 100 buyers. The firms' widgets are undifferentiated, and the firms know each others' costs and capacities. Furthermore the firms are playing a one-time pricing game; widgets are obsolete after this one selling opportunity. Each buyer is interested in purchasing a single widget, and has an RP of $10.

Firm A has lower costs than Firm B, but also has lower capacity. Specifically, their (constant) marginal costs and capacities are as follows.

   Finally, assume that each firm can only post prices in whole dollar amounts. (This question is motivated by firms selling through coin-operated vending machines. It is too costly to stock such machines with pennies, so sellers must set prices in fixed increments of larger denomination coins.) Throughout this entire problem, firms may only choose prices of $1.00, $2.00, $3.00, ..., up to $10.00. Firms may NOT use prices such as $1.50, $2.99, $3.83, etc.

(2a.) Find equilibrium prices for this one-time pricing game. (As usual: all buyers go to the firm with the lowest price. However if Firm A's price is no higher than Firm B's price, Firm A serves only 30 buyers, and the rest go to Firm B. Your answer should be a pair of prices, one for each firm.)

(2b.) Suppose that before the pricing game starts, Firm A can build a production plant that would have full capacity of 100 units. (Marginal costs would remain the same, and Firm B would see Firm A's new capacity. Then firms would simultaneously set some equilibrium prices.)

Ignoring the cost of building, how much profit would Firm A earn if it expanded?  Firm A would now earn profits of ______________. (You must show your calculations for credit. The same assumptions apply as the previous part, except now the firms split the market 50/50 if they price equally.)
