An asset for drilling was purchased and placed in service by a petroleum production company. its cost basis is $60,000, and it has an estimated market value of $12,000 at the end of an estimated useful life of 14 years. compute the depreciation amount in the third year and book value at the end of the fifth year of life using sl method and 200% db method with switchover to sl. in which year does the switchover happen?

What is a monomer? how do they form a ploymer from the view point of chemical bonding?

An external consultant recommends that a plant installs a bank of capacitors for power factor correction. this will reduce the peak electrical demand charges by an average of 93 kw every month. the plant current pays $13 per kw in peak demand charges. the capacitor bank will include 223 kw of fixed capacitors, and 183 of variable capacitors. the fixed capacitors cost $59 per kw, and the variable capacitors will cost $65 per kw. the consultant charges 21% of the equipment costs to install the capacitors. because this project will reduce the demand for the electric utility, they are prepared to provide a one-time rebate of $42 per kw of reduced demand. what is the simple payback period for this project (in years)?
