An octapeptide was isolated from a fungus for use as a new antibiotic. The composition of the peptide was 2 Gly, Lys, Met, Pro, Arg, Trp, Tyr. Edman degradation of the intact peptide yields FDNB- glycine. The peptide was then treated with carboxypeptidase A, B and C, only carboxypeptidase C had any effect cleaving off Pro. The peptide was then treated with trypsin (cleaves at Arg and Lys), which gave two tripeptides and a dipeptide.   The compositions of the tripeptides were Met, Lys, Tyr, and Arg, Trp, Gly. The peptide was digested with chymotrypsin (cleaves at Trp, Phe and Tyr), which yielded two tripeptides and a dipeptide. Acid hydrolysis of the dipeptide from chymotrypsin yielded only glycine (hint acid hydrolysis had two problems).

a. You are in the market for a new refrigerator for your company’s lounge, and you have narrowed the search down to two models. The energy-efficient model sells for ¢1,700 and will save you ¢45 in electricity costs at the end of each of the next five years. The standard model has features similar to the energy-efficient model but provides no future saving in electricity costs. It is priced at only ¢1,500. Assuming your opportunity cost of funds is 6 percent, which refrigerator should you purchase? b. You are the human resources manager for a famous retailer and are trying to convince the president of the company to change the structure of employee compensation. Currently, the company’s retail sales staff is paid a flat hourly wage of ¢20 per hour for each eight-hour shift worked. You propose a new pay structure whereby each sales- person in a store would be compensated ¢10 per hour, plus 1 percent of that store’s daily profits. Assume that, when run efficiently, each store’s maximum daily profits are ¢25,000. Outline the arguments that support your proposed plan.

An auto dealership is advertising that a new car with a sticker price of $34,128 is on sale for $25,995 if payment is made in full, or it can be financed at 0% interest for 72 months with a monthly payment of $474. Note that 72 payments × $474 per payment = $34,128, which is the sticker price of the car. By allowing you to pay for the car in a series of payments (starting one month from now) rather than $25,995 now, the dealer is effectively loaning you $25,995. If you choose the 0% financing option, what is the effective interest rate that the auto dealership is earning on your loan? (Hint: Discount the payments back to current dollars, and use Goal Seek to find the discount rate that makes the net present value of the payments = $25,995.)

Enter your answer as a percentage. If required, round your answer to one decimal digit.

1. The Lathe

You are considering the purchase of a new lathe to expand production of a hot product line. The lathe costs $280. It will have a life of four years. You will depreciate the lathe to zero book value using straight-line depreciation over four years. At the end of four years, you will sell the machine for $50. The new lathe will generate cash sales of $230 per year, and operating costs will run $120 per year. The firm will need to carry additional inventory of $30, accounts receivable of $30, and cash balances of $10. There is no material impact on accounts payable. The corporate tax rate is 40%. Assume the additional working capital requirements are incurred at the start of the project (t = 0) and are recovered in Year 4. The discount rate is 8%.

Assume all cash flows last for four years.

1. Use a table similar to the following to estimate the total cash flows from the project.

2. Assume the cash flows from (A) are the following:
