   Question 148035: An item costs \$1300 has a scrap value of \$100, and a useful life of six years. The linear equation relating book value and number of years is:Answer by josmiceli(10616)   (Show Source): You can put this solution on YOUR website!The data given tells me two points on the linear relation (,) (,) This is with ,the book value plotted on the y-axis and , the number of years on the x-axis says that when it's years old (brand new), it's worth dollars says that when it's years old, it's worth dollars (scrap value) The formula to use, in terms of B, and n is multiply both sides by multiply both sides by answer Try values of n = 1,2,3,4,5,6 to check this
