An investor company owns 30% of the common stock of an investee company. The investor has significant influence over the investee, and acquired its equity interest in the investee on January 1, 2018 for $525,000. On the date of acquisition, the investee’s stockholders equity was $1,500,000, and the fair values of the investee’s individual net assets were equal to their reported book values. During the year ended December 31, 2018, the investee reported net income of $50,000 and dividends of $10,000. During the year ended December 31, 2019, the investee reported net income of $60,000 and dividends of $15,000. The investor routinely sells inventory to the investee at a 25% profit margin. At December 31, 2018 and 2019, the investee held inventories purchased from the investor for $30,000 and $40,000, respectively. (At the end of each period, all of these inventories are sold by the investee to unaffiliated companies in the next period.)

What is the balance in the Equity Investment account on December 31, 2019?

Select one:

a. $ 525,000

b. $ 547,500

The very long cylindrical solenoid of (Figure 1) has a radius of 0.50 m and 1000 windings per meter along its length. A circular conducting loop of radius 1.0 m encircles the solenoid, with the long central axis of the solenoid passing through the center of the loop, and with the area vector of the loop parallel to the solenoid axis. The solenoid initially carries a steady current I, but the current is then reduced to zero during a 0.100-s time interval.

Part A

If the average emf induced in the loop during that interval is 0.80 V , what was the initial current magnitude?

Problem 2. Consider a duopoly with identical firms with no fixed cost and marginal cost of c. Let the
inverse demand curve for the industry be p(Y ) = A − bY , where Y is the total industry output. Let y1 and
y2 be the output of each firm. Assume that the firms in the industry each choose quantity, and then let the
market determine the price they will receive.
(a) Compute the total market output, the price, the quantity for each firm, and the profit for each

firm, under Cournot competition. Make sure to start at the beginning, setting up each firm’s profit-
maximization problem and proceeding from there.

(b) Compute the total market output, the price, the quantity for each firm, and the profit for each firm, if
the firms collude and choose their quantities together to maximize total profits. Assume that they split
the total output evenly. Again, make sure to set up the joint profit-maximization problem and proceed
from there. [Hint: you will find that you cannot solve the system of two first-order conditions. Indeed,
you will find that the two first-order conditions are identical, leaving you with only one equation with
two unknowns. To solve this problem, simply take advantage of the assumption that they split the
market evenly, y1 = y2. Now you have two equations with two unknowns.]
(c) Now suppose that one firm sticks to the collusive quanity, while the other one cheats. Compute the
profit maximizing output of the cheater, the market price, and the profit for each firm.

(d) Using the results you have computed above, argue that the collusive agreement is not a Nash equi-
librium. In addition, argue that if firms have common knowledge of rationality (each knows that the

other is rational, and knows that the other knows they are rational, etc) the only Nash equilibrium is
for both firms to choose the Cournot equilibrium quantity.
(e) Again, using the results you have computed above, argue that this situation can be thought of as a
prisoner’s dilemma. (Recall that we characterized a prisoner’s dilemma as a situation in which agents
are unable to cooperate, even when to do so would maximize their individual payoffs, because the
private cost of cooperation is greater than the private benefit of cooperation.)

Question: State if an algorithm (satisfying the formal definition of an algorithm) which is guaranteed to find a solution exists or not for each of the following problems by filling the blanks with “Yes” (an algorithm guaranteed to find a solution exists) or “No” (an algorithm guaranteed to find a solution does not exist).

1. Finding the average height of a person in a group, given the height of each person in the group

2. Finding all factors of a finite integer

3. Finding if a triangle is scalene or not, when the coordinates of its vertices are given

4. Finding a path from the given start location to the given goal location in a finite maze (the number of junctions is finite and the length of path connecting any two junctions is also finite) that changes unpredictably at any time

An electron is constrained to the central perpendicular axis of a ring of charge of radius 2.3 m and charge 0.020 mC. Suppose the electron is released from rest a distance 0.056 m from the ring center. It then oscillates through the ring center. Calculate its period. (The electron is always much closer to the ring center than a radius.)

Define dumping. Differentiate the tree types of dumping which one is to be welcomed and which one is to be opposed and why?

SecuriCorp operates a fleet of armored cars that make scheduled pickups and deliveries in the Los Angeles area. The company is implementing an activity-based costing system that has four activity cost pools: Travel, Pickup and Delivery, Customer Service, and Other. The activity measures are miles for the Travel cost pool, number of pickups and deliveries for the Pickup and Delivery cost pool, and number of customers for the Customer Service cost pool. The Other cost pool has no activity measure because it is an organization-sustaining activity. The following costs will be assigned using the activity-based costing system:

The distribution of resource consumption across the activity cost pools is as follows:

Required:

Complete the first stage allocations of costs to activity cost pools.

9. The decomposition of N₂O₅is first order with a rate constant of 4.80 x 10^-4 s^-1at 45 ºC. If the initial concentration is

1.65 x 10^-2 M, what is the concentration after 825 s? What is the half life? How long would it take for the concentration of N₂O₅ to decrease to 1.00 x 10^-2 M from its initial value?
