You are encouraged to research outside sources and, of course, cite them. Do not, however, quote sources word-for-word, but rather, respond to the Discussion Forum Question in your own words.
1. Identify four reasons that capital budgeting decisions by managers are risky.
2. Why is an investment more attractive to management if it has a shorter payback period?
3. Why should managers set the required rate of return higher than the rate at which money can be borrowed when making a typical capital budgeting decision?
4. Why does the use of the
accelerated depreciation method (instead of straight line) for
income tax reporting increase an investment’s value?
After you’ve completed the questions above, please provide a brief explanation of how this information is important in managerial decision making. (500 minimum word count, references excluded)

Code a class encapsulating a queue of foods using a circular array. A food has the following attributes: name, the number of calories per serving and the number of servings per container. Limit your queue to 20 food items. In addition to writing the enqueue, dequeue, and peek methods, you will write two more methods: a method that returns the average calories per serving of all the foods in the queue; a method that returns the food items with the highest total calories (ie: number of calories per serving * servings per container). Write a program to test your queue with all these methods

A billiard ball of mass mA = 0.400 kg moving with a speed vA,0 = 1.80 m/s strikes a second ball, initially at rest, of mass mB = 0.500 kg. As a result of the collision, the first ball is deflected off at an angle of 30.0 o with a speed vA = 1.10 m/s.
a) What is the speed vB and angle of deflection θB of ball B? Take the x axis to be the direction of motion of ball A before the collision.
b) Is the collision elastic? You must support your answer with a calculation.

Section I: Derivation of Hicksian Demand Curve
Joyce’s utility function is as follows:
U= 10X3Y2
Where, X, is the quantity of good X consumed, Y, is the quantity of good Y consumed and, U, is Joyce’s utility function.
The general budget constraint for the two goods is a follow:
B= PXX + PYY
Derive Joyce’s Marshallian demand equation for good X. Also compute her demand for good X when B= 500, and the price of good X is 1 and 2. Also draw the Marshallian demand curve for X at these prices.
What is Joyce’s optimal amount of good Y purchased if PY= 1 and Px=1 and if Px=2 and PY= 1?
Derive the Hicksian demand for good X at these prices. Hint, you need to choose the three correct equations you’ve derived above and solve simultaneously. Also, draw both demand curves on the same graph.
Using the information derived in parts A and B, what is the substitution effect and income effect obtained when changing the price of good x from a value of 1 to a value of 2.

Bay Area Limos operates transportation services to Bay City airport. The price of service is fixed at a flat rate for each trip and most costs of providing the service are fixed for each trip. Betty Smith, the owner, forecasts income by estimating two factors that fluctuate with the economy: the fuel cost associated with the trip and the number of customers who would take trips. Looking at next year, Betty develops the following estimates of contribution margin (price less variable costs, including fuel) for the estimated number of customers. For simplicity, she assumes that the fuel costs (therefore the contribution margin per ride) and the number of customers are independent. |
| Contribution Margin per Ride |
||
| Scenario | (Price - Variable cost) | Number of Customers |
| Excellent | $ 45 | 5,500 |
| Fair | 35 | 2,800 |
| Poor | 20 | 2,200 |
|
In addition to the costs of a ride, Betty estimates that other service costs are $42,000 plus $6 for each customer (ride) in excess of 2,800 rides. Annual administrative and marketing costs are estimated to be $20,000 plus 10 percent of the contribution margin. |
| Required: |

Compute the total contribution, costs and operating profit for each of the scenario and each group of customer. (Input all amounts as positive values except losses which should be indicated with a minus sign. Omit the "$" sign in your response.) |

I'm trying to write a code that asks for double values and counts how many times 2 consecutive values differ by at most 1. The output on 0 should be the answer.
With inputs 1, 1.7, 0.8, -0.1, -1, 0 : it should return 4 but keeps giving me 0. This is the correct output because only 1 and 1.7 differ by at most 1 as does 1.7 and 0.8, 0.8 and -0.1, and -0.1 and -1. We do not check whether 0 is within 1 of the previous number because 0 is the input that causes us to exit.
Why is this if every time a number differs by at least one my if statement should n++?
#include <iostream>
using namespace std;
int main ()
{
double n1, n2 = 0;
int n = 0;
cout << "Enter a number." << endl;
cin >> n1;
while (n1 != 0) {
if ((n1 - n2) > -1
&& (n1 - n2) < 1) {
n++;
n1 =
n2;
}
else {
cout
<< "Enter another number or 0 to end." << endl;
cin
>> n1;
}
}
cout << n << endl;
return 0;

You are the director of international operations for North and South America for Lenovo. In 2015 you developed a five-year marketing plan to aggressively market personal computers in Canada, Mexico and Brazil. A key element of your plan called for meeting the competitive prices of HP and local manufacturers every step of the way. In addition you planned to spend heavily on marketing. Your yearly budget for marketing in the major target markets was set as follows:
Canada C$ 2,000,000
Mexico Pesos 5,000,000
Brazil Reals 1,000,000
Your 2015 price set in U.S.$ for your top selling laptop was $2,000 in each market. Market prices have declined 20% on a U.S$ basis over the years.
1. What do your marketing budgets look like in 2015 and today in US$?
2. What do the computer prices look like in local currencies in 2015 and today?

Use the classical model for determining the long-run outcome of the economy to answer the following question. Suppose a government in debt crisis (such as Greece) moves to reduce its budget deficit by reducing the annual funding for tertiary education and healthcare drastically.
(a) Graphically illustrate the impact of such a reduction in the government's budget deficit:
i. First, by assuming that the total factor productivity (TFP) does not depend on the government spending on health and education.
ii. Second, by assuming that the TFP increases with government spending on health and education but by a limited amount. [Be sure to label: the axes; the curves; the initial equilibrium values; the direction curves shift; and the terminal equilibrium values.]
(b) State and explain in words what happens to the real interest rate, national saving, investment, consumption, and output.
(c) Discuss the likely impact of such policy on the inequality of income between the educated and uneducated labour. Support your answer with graphical illustrations.
(d) Suppose the above policy causes a sudden emigration of workers with no education to neighbouring countries for easier access to education and health facilities. Assume TFP does not decrease following the government policy shock, as in part a (i), and following the labour migration. How would your answer to (b) and (c) change?
