TES ASK YOUR TEACHER PRACTICE ANOTHER When filing income tax returns, many people can claim deductions for depreciation on items such as cars and computers used for business purposes. The idea is that the value of such an asset decreases, or depreciates, over time. The simplest method used to find the depreciated value is called straight-line depreciation, which assumes that the item's value decreases as a linear function of time. (a) If a $1,700 computer system depreciates completely in five years, find a formula for its value V as a function of time t. V = 1700 - 340x3 X What is it worth after three years? $ 5 X (b) Suppose a computer system of the same cost depreciates completely in three years. Find a formula for its value C as a function of time t. (Round your coefficients to one decimal place.) C = 566.66 X
