3. A company decides to produce a new product which requires buying equipment for $4000. Revenue is expected to be S1500 in year 1, and increase by $500 every year. The project will last 4 years, at which time the equipment can be sold for $600. a. Draw the cash flow diagram for this project. (10 points) b. What is the present worth of this project, if interest is 8%? (10 points)

1. (a) Microorganisms can be used to remove chemical pollutants from the environment. ine gene cluster xyl encodes several enzymes that are involved in degrading toluene, and transcription of these genes is activated when the xylS protein (expressed continuously under a constitutively active promoter p) binds to toluene. Only then can the resulting xyls/toluene complex bind to the pm promoter to activate transcription of the genes in the xyl cluster. By considering the cellular location of the enzymes that degrade...

Suppose you are a network systems provider and are bidding for the job of providing and installing a system for a new government office building. You are considering submitting one of three bids: a low bid of $500,000, a medium bid of $600,000, and a high bid of $700,000. The cost of the job to you will be $450,000, regardless of your bid. Thus, if you submit a bid of $500,000 and win the contract, your profit will be $500,000...
