A consumer finds only three products, X, Y, and Z, are for sale. The amount of utility which their consumption will yield is shown in the table below.

Assume that the prices of X, Y, and Z are $10, $2, and $8, respectively.

The consumer has an income of $74 to spend.

(a)          Complete the table by computing the marginal utility per dollar for successive units of X, Y, and Z to one or two decimal places.

(b)          How many units of X, Y, and Z will the consumer buy when maximizing utility and spending all income?

(c)           Why would the consumer not be maximizing utility by purchasing 2 units of X, 4 units of Y, and 1 unit of Z?

Given: You are given a Python Class template. In this class there is a
class variable vector, is a list of N non-negative integers and are
stored (in positions 0, 1, 2, ... (N-1)), where at least one integer
is 0.

Task: Write a recursive function "findAllPaths" to find all possible
path through V starting at position 0, and ending at
the location of 0, in accordance with the Rule below.
If no such path exists, "paths" should be an empty list. You also
have to write functions called "getShortest" and "getLongest" which
return respectively the shortest and longest paths as lists.

Rule: From position i, the next position in the path must be either i+x,
or i-x, where x is the non-negative integer stored in position i.
There is no path possible from position i to position i+x if
either of these 2 conditions hold:
position i+x is beyond the end of V.
position i+x is already on the path.
There is no path possible from position i to position i-x if
either of these 2 conditions hold:
position i-x is beyond the start of V.
position i-x is already on the path.

Example:
Suppose V contained the following:
Position: 0 1 2 3 4 5 6 7 8 9 10 11
Integer: 2 8 3 2 7 2 2 3 2 1 3 0
Then one path is:
0 2 5 7 4 11

Recursive Algorithm
-------------------
Your solution MUST use a recursive function to identify the paths.

You must implement the recursive function, as follows:

def findAllPaths(self, position, solution):

"findAllPaths" takes the initial part of a solution Path, and
a potential next solution position in the Vector. It explores
paths with the given position appended to the given solution
path so far.

The class variable paths is a list of lists and the function

Example Run:
------------
Example vector: [2, 8, 3, 2, 7, 2, 2, 3, 2, 1, 3, 0]
Valid paths:
0 2 5 7 4 11
0 2 5 3 1 9 10 7 4 11
0 2 5 3 1 9 8 10 7 4 11
0 2 5 3 1 9 8 6 4 11

No Solution example:
3 1 1 1 3 4 2 5 3 0

The following template is given:

def getName():
# Use the name displayed on D2L (easier for us to find)
   return "Haque, Mohammad"
  
class Pathfinder():
def __init__(self, vector):
# Initialize the Pathfinder object
self.vector = vector
self.paths = []
self.findAllPaths(0,[])

def findAllPaths(self, position, solution):
# Recursively explore the possible paths and store valid paths
# This method will not be tested, so you can modify the parameters as needed
print("hi")
pass

def getLongest(self):
# Return the longest of all paths found or [] if no paths exist
# If multiple paths with the longest length exist, return one of them
pass

def getShortest(self):
# Return the shortest of all paths found or [] if no paths exist
# If multiple paths with the shortest length exist, return one of them
pass

Any help will very much appreciated

1. Prepare journal entries to record the events [7 Marks]

Many regions in North and South Carolina and Georgia have experienced rapid population growth over the last 10 years. It is expected that the growth will continue over the next 10 years. This has motivated many of the large grocery store chains to build new stores in the region. The Kelley’s Super Grocery Stores Inc. chain is no exception. The director of planning for Kelley’s Super Grocery Stores wants to study adding more stores in this region. He believes there are two main factors that indicate the amount families spend on groceries. The first is their income and the other is the number of people in the family. The director gathered the following sample information.

Food and income are reported in thousands of dollars per year, and the variable size refers to the number of people in the household.

The table below shows a sample of 100 companies firms that were targets of tender offers during the period 1975–1985. A tender offer is an offer to purchase some or all of shareholders' shares in a corporation. The price offered is usually at a premium to the market price. Conduct an analysis where the response variable represents the number of bids (BIDS) received preceding the takeover of the firm. The explanatory variables include the bid premium (PREMIUM) and firm size (SIZE). In general, it is reasonable to expect that a high initial bid premium, defined as the percentage excess of the firm's stock price, would discourage subsequent bids. Additionally, while tender offers for large corporations are likely to receive more media exposure and thus attract the attention of opportunistic bidders, the size of the firm also will act as deterrence mechanism given the wealth constraint that will impose to potential bidders.
