Software Evolution:

1. Mention one reason why software change is unavoidable.

2. Suppose two system maintenance requests have emerged for the in-store automated

supermarket system in the following situations:

Situation 1: A new payment method (e.g., Bitcoins) is

needed to be added to the system.

Situation 2: This situation is based on the mix payment method where a customer can use

multiple methods of payments, such as cash and card, in a single transaction. Suppose a customer

decides to pay using cash and card. The customer first pays a portion of the full amount through

cash and then the balance using the card. In this case, it has been identified that the system

incorrectly charges the amount paid in cash from the card instead of the balance and completes

the transaction.

a. Specify what categories of system maintenance are described above.

b. Assume that you are performing an impact analysis of the changes. Identify a

consequence that could occur due to each of changes requested above.

We are evaluating a project that costs $880,000, has a life of 14 years, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the project. Sales are projected at 146,000 units per year. Price per unit is $38, variable cost per unit is $23, and fixed costs are $894,080 per year. The tax rate is 22 percent, and we require a return of 11 percent on this project.

Cows are munching down zucchini, yellow squash and cabbage that Southern Valley Fruit and Vegetable farms grew and picked for restaurants and other institutions.

It’s one way the company is trying to make use of the glut of south Georgia vegetables caused by the closure of dining spots, schools and other big buyers. South Georgia farmers ship food from Florida to Canada, but the closures cost them 40- to 50% of their market. Growers are caught between being unable to sell all their crop and selling what they can in a flooded market with dropping prices. [Atlanta Journal and Constitution, May 3, 2020]

1. Draw a demand and supply diagram that illustrates the changes taking place in the vegetable market. Explain any changes you draw.
2. Assume vegetable farms operate in a perfectly competitive market. Draw a cost and revenue diagram that shows the effect on farms profits of “dropping prices"

Towing Company manufactures and sells a single product for $40 per unit.
Variable costs are $30 per unit and fixed costs total $168,000. During
2019, the company sold 26,500 units of this product to customers. In
order to improve profitability, the president of Towing Company believes
the following changes should be made in 2020:

1. decrease the selling price of the product by 10%

2. automate a portion of the production process which will reduce
   variable costs by 5% per unit but will add an additional fixed
   cost of $16,310 per year

3. increase advertising by $49,420

Assume these changes are made. 
A) Calculate the number of units that Towing Company must sell in 2020 in order to earn a net income that is 20% greater than the net income earned in 2019.

B) Calculate the number of units that Towing Company must sell in 2020 in order to earn a target profit equal to 12% of sales.

1. You are asked to analyze each of the following events using the Solow growth model (the events all happen at time 0): a) The investment rate rises in Tanzania. b) Immigration increases the population of France by 10%. c) An earthquake destroys 10% of the capital stock of Chile. (Hint: does steady state GDP per capita change in Chile?) d) Malaysia realizes a 10% rise in TFP due to technology transfer.

For each of these: Draw a Solow diagram to show what happens when the economy is initially in steady state. Explain how steady-state GDP per capita changes. Use algebra to help in your explanation. Does steady-state capital per capita change? Explain how the growth rate of GDP per capita changes at time 0. Explain how the economy adjusts from the short run to the long run after the change
