Hello, This is for a Principles of cost engineering class, any help would be HUGELY appreciated.

Please use the compound interest tables for 8% and 10% provided in the link to assist you with completing this assignment. SHOW AND/OR EXPLAIN YOUR WORK IN YOUR RESPONSE. Answers without substantiation will receive zero points. Complete the following problems: 1. (10 pts) the following chart shows ending of period cash flow for expenses. The interest rate is 10 percent. What is the net present worth (value) of this cash flow? Year Expenses 100 1 100 2 3 100 4 100 5 100 2. (10 pts) You are evaluating an alternative that requires an initial investment of $50,000. The following chart shows ending period cash flow of annual savings. The interest rate is 10 percent. What is the net present worth (value) of this investment alternative? Year Savings 1 $2,667 2 $14,292 3 $19,181 4 $13,114 3. (10 pts) A production operation in a company is performed with equipment on-hand and labor costs of $75,000 per year. The equipment is very low-maintenance and should last indefinitely. A new equipment item for the same operation, also very low- maintenance but requiring replacement every 6 years, can be purchased for $170,000. It will cut labor costs in half. The firm's minimum attractive rate-of-return (MARR) is 10 percent. (a) Should the company buy the new equipment. Explain why or why not? (b) What is the internal rate of return of the alternative whereby the new equipment is purchased? Show your work in your response. 4. (20 pts) A charity organization is seeking help to analyze the contribution pattern. The objective is to develop the budget to fund worthy projects. You are being called upon to share your expertise. The first step is analyzing contribution checks received. You have randomly selected ten checks with the following contribution amounts: $15, $10, $25, $10, $5, $10, $30, $20, $10, $15 (a) Calculate the mean, median, and mode of these contributions. Show your work in your response. (b) What is the range of contributions? (c) What is the variance of the contributions?
