The Al Best Company uses a 7.5-kW motor for 16 hours per day, 5 days per week, 50 weeks per year in its flexible work cell. This motor is 85% efficient, and it is near the end of its useful life. The company is considering buying a new high efficiency motor (91% efficient) to replace the old one instead of buying a standard efficiency motor (86.4% efficient). The high efficiency motor cost €70 more than the standard model, and should have a 15-year life. The company pays €7 per kW per month and €0.06 per kWh. The company has set a discount rate of 10% for their use in comparing projects. Assume the load factor is 60% Determine the SPP, ROI, and BCR for this project:

Spencer Kars provides shuttle service between four hotels near a medical center and an international airport. Spencer Kars uses two 10-passenger vans to offer 12 round trips per day. A recent month’s activity in the form of a cost-volume-profit income statement is shown below.

A. Calculate the break-even point in dollars.

B. Calculate the break-even point in number of fares. (Round answer to 0 decimal places, e.g. 5,275.)

C. Without calculations, determine the contribution margin at the break-even point.

Draft a document addressing the following topics:

1. Identify the differences between all four market structures in the short-run and long-run. This will be helpful as many of you may hold management positions and/or become entrepreneurs in the near future. When deciding what type of firm to own or operate, you may find that one market structure may be more advantageous over another based on short-run and long-run costs.

2. Explain the significance that the average total cost (ATC) curve has on profit and loss based on each type of market structure. Explore how the ATC curve affects all four market structures and identify whether firms will earn a profit or loss based on the placement of the ATC curve and price.

Write in C# please! Ask the user to enter all of their exam grades. Once they are done, calculate the minimum score, the maximum score and the average score for all of their scores. Perform this using at least 2 Loops (can be the same type of loop) and not any built in functions.

Design in java a multiple recursive version of Tetranacci calculators. You will calculate Tetranacci(5), Tetranacci(10) and measure the corresponding run times. (for instance, Tetranacci(10) returns 56). You can use Java’s built-in time function for finding the execution time.

Pointers is a difficult concept for many students.  I'm not sure how to make students understand the concept better. In an attempt to have you try to understand pointers, I'm going to ask you to write a paper that summarizes the chapter (or an online resource) that may help you understand the concept of pointers. Include the following topics in the paper. Include illustrations either from the book, or an online source or your own illustration.

• Come up with an introduction
• Pointer Variable Declarations and Initialization
• Pointer Operators
• Pass-by-Reference with Pointers
• Built-In Arrays
• Using const with Pointers
• sizeof Operator
• Pointer Expressions and Pointer Arithmetic
• Relationship Between Pointers and Built-In Arrays
• Pointer-Based String
• About Smart Pointers

You may include additional topics and illustrations to maybe help someone else understand the concept. Upload your final paper to this assignment page.
