answer all questions please.

1) A person invested SR X in an account that pays Y% compounded annually. The first withdraw happens at the end of year 3. The payments increase at 5% every year until the end of 6th year. Thereafter, the payments decrease by SR Z every year. The planning horizon is W years. Calculate the value of the first withdraw such that this investment is attractive (Use PW analysis) Serial Number 1-5, 36-39, and 70-77 6-10 and 65-69 11-15 and 60-64 16-20 and 55-59 21-25 and 50-54 26-30 and 45-49 31-35 and 40-44 Value of X Value of Y Value of Z Value of W 1,000,000 5% 1,000 15 1,200,000 10% 2,000 17 1,500,000 15% 3,000 15 1,700,000 5% 4,000 17 2,000,000 10% 5,000 15 2,200,000 15% 1,000 17 2,500,000 5% 2,000 15 2) A technology company is planning to purchase one of two chips. Due to the pace of technological change in this area, it is realistic to assume that these are one-shot investments. The expected cash flows for each machine are shown below. MARR is P % per year.

The first project has a construction cost of SR X. The operating cost is SR 40,000 annually and maintenance is required every 5 years of the amount SR Z. The second project has a one-time initial cost SR Y with an annual operating cost of SR 80,000 and requires maintenance of SR W every 3 years. Assume R% MARR. Using capitalized cost analysis, calculate the CC for the first and second projects and then decide which alternative should be chosen.
