The automobile has depreciated $ (Simplify your answer.) over the 7 years A business uses straight-line depreciation to determine the value y of an automobile over a 7-year period. Suppose the original value (when t = 0) is equal to $15,500 and the salvage value (when t = 7) is equal to $5000 a. By how much has the automobile depreciated over the 7 years? b. By how much is the value of the automobile reduced at the end of each of the 7 years? c. Write the linear equation that models the value s of this automobile at the end of year t. The value of the automobile is reduced by $ at the end of each of the 7 years. (Simplify your answer.) The linear equation that models the value s of this automobile at the end of yeart is s = (Simplify your answer. Do not factor. Type an expression using t as the variable.)
