Company is primarily an athletic apparel and shoe manufacturer. Company will be producing athletic shoes and equipment mainly targeting youth and sports men. However, it products range will also include items which could be used by people of any age. Therefore, it can be stated that though, company is primarily producing products for young generation but it will also have segments targeting people from all sizes, and ages.

a.

P= It is the price of good which company is selling

M=M represents the income of the consumers, which can change with time. SO it can change and is a variable is the equation

PR= This is the price of the related goods, which can change and can attract the consumers to switch products or substitute them for Sultan’s Athletic products

This shows the taste patterns of the consumers in the market

Pe= This is the expected price of the product in some future period

Expected price of the product in some future period

N= There no special number all consumers buy shoes even if they are not        exercising

b.

The variables which could affect the supply  side of the equation are given below:

P= It is the price of good which company is selling

PI= This is the price of raw material or inputs used in the manufacturing of shoes, clothes and other equipment.

Pr= It is the prices of related goods in the market which competitors are trying to sell.

T= It defines the available technology in the market used by the manufacturer

Pe= It is the producers price expectations based on the inflation projected by the central bank.

F= It represents the number of similar fi9rms which are operating in the industry.

The table shows that the total benefit is incresaing with the total cost as wll whereas the total cost is greater then the total benefit. The marginal benefit is declining with the increase in the value of A, and the marginal cost is increasing.

The graph shows the curve of the total benefit and total cost. The total cost is greater than the total benefit at the highest value of A.

b.

This graph shows the declining trend of the marginal benefit and the increasing trend of the marginal cost.

According to this chart, look at the point of intersection between MB and MC. They intersect at Unit 21. It means that company should manufacture 21 units.

c.

i. MB at half A is 125

ii. MC at half A is 132

iii. But, if we continue producing more, company can produce 41 units where MB=MC. This is the optimal point.

d.

i. MC is 20.5

ii. MB  is 20.5

iii. If company will go beyond this point, it will only incur loss. Therefore, optimal point is that company only makes 10 units.

e

These estimations may not be practical for the company. Since, Company is expected to make thousands of dollars. How is it possible that it only makes only 21, 41 or 10 units in different scenarios? Therefore,   the model may not be a realistic presentation of the real scenario, where sports manufacturers make healthy sales and units.

a.In this business of sport apparel and shoes, like any other business, many variables affect the demand and supply of the company’s products. Here, what’s important is to determine that how each factor will have an impact on the dependent factor in the model.  SO, all these factors must be factored out which could realistically have a profound impact on demand of the company’s products.

b. Dependent variable in this project is the demand for the products of Sultan’s Athletics Store. Independent variables are all the variables which could have effect on the demand of the product. These are on the right side of the equation stated above.

c. Regression Analysis

Here, regression is run by keeping the other variables constant and effect of price on demand is determined here. Result is depicted in following table:

d. Interpretation:

Two important pieces of information here given here are:

Intercept:  Value of intercept is 760.109, it depicts that whether there is high price or lower price, this demand of 760 will be there. So, it is autonomous demand for the product of Sultan.

Slope: Slope of -53 indicates the negative relationship between the demand and price of Sultan Apparel.It means that if the price increase by 1 unit, demand will decline by 53.

Similarly, if the values for other independent variables are available, regression can apply for those as well to see the impact on demand of the products.

e.

If the price is changed, it can produce different results. This is shown in the following regression models:

If Price increases by 1, we get

The graph shows that the marginal utility of other products is lower at first but is greater with the increase in the units, whereas it is vice versa for our product.

Based on the results the consumer would consume first 8 units of our product and then use 3 units of Other product in order to maximize its revenue

This graph shows that the marginal profit has a curving trend, first increasing and then decreasing constantly, whereas the marginal cost is relatively constant and is well below the marginal profit.

b.

This graph shows that the major part of the average cost is not based on the average variable cost and is held fixed in nature.

c. This graph shows the relation between the marginal and average profit, which n this case has the same trend of increasing and then decreasing, however the marginal profit is greater in value than the average profit.

d.

This graph shows the relation between the marginal cost and average variable cost, depicting the high average variable cost as compared to the marginal cost, and that the MC has a declining trend whereas the AVC has an increasing trend.
