Suppose that a major city’s main thoroughfare, which is also an interstate highway, will be completely closed to traffic for two years, from january 2014 to december 2015, for reconstruction at a cost of $535 million. if the construction company were to keep the highway open for traffic during construction, the highway reconstruction project would take much longer and be more expensive. suppose that construction would take four years if the highway were kept open, at a total cost of $800 million. the state department of transportation had to make its decision in 2014, one year before the start of construction (so that the first payment was one year away). so the department of transportation had the following choices: (i) close the highway during construction, at an annual cost of $267.5 million per year for two years. (ii) keep the highway open during construction, at an annual cost of $200 million per year for four years. now suppose the interest rate is 80%. calculate the present value of the costs incurred under each plan.

Scientists developed the first successful human cell culture in vitro (grown in a lab) in the 1950s by removing cancer cells from a woman. this concept has allowed modern scientists to successfully grow organs. which of the following answers  bestdetermines why there was success?   neurons send a signal to the cell to multiply. a large blood supply to the cell allows enough nutrients for growth. cells are the basic unit of life and thus can regenerate if in a controlled environment. cells cannot reproduce on their own, and the scientist manipulates them to grow.
