Straight-line depreciation is an accounting method used to help spread the cost of new equipment over a number of years. It takes into account both the cost when new and the salvage value, which is the value of the equipment at the time it gets replaced. The function where V is value and t is time in years, can be used to find the value of a large copy machine during the first 4 years of use. What is the value of the copier after 1 years and 3 months?
