The first MRSA case was discovered in 1961 in a British hospital and was the result of a mutation in the enzyme normally inhibited by the b-lactam ring of methicillin. The site where the antibiotic would bind no longer allowed access to the ring, so the enzyme continued functioning normally. The microbe acquired a new gene that, when made into protein, was a different version of PBP, one that couldn’t be inhibited by penicillin. Questions 1. What other mechanisms might arise to allow resistance to the b-lactam antibiotics? 2. Could resistance arise to vancomycin? Why or why not?

(Net present value calculation) Carson Trucking is considering whether to expand its regional service center in Mohab, UT. The expansion requires the expenditure of $9,500,000 on new service equipment and would generate annual net cash inflows from reduced costs of operations equal to $2,000,000 per year for each of the next 9 years. In year 9 the firm will also get back a cash flow equal to the salvage value of the equipment, which is valued at $1.2 million. Thus, in year 9 the investment cash inflow totals $3,200,000. Calculate the project's NPV using a discount rate of 10 percent. If the discount rate is 10 percent, then the project's NPV is $
