During April, the first production department of a process manufacturing system completed its work on 375,000 units of a product and transferred them to the next department. Of these transferred units, 75,000 were in process in the production department at the beginning of April and 300,000 were started and completed in April. April's beginning inventory units were 60% complete with respect to materials and 40% complete with respect to conversion. At the end of April, 97,000 additional units were in process in the production department and were 80% complete with respect to materials and 30% complete with respect to conversion. Compute the number of equivalent units with respect to both materials used and conversion used in the first production department for April using the weighted-average method

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.
