1. The problem statement, all variables and given/known data For tax and accounting purposes, corporations depreciate the value of equipment each year. One method used is called "linear depreciation," where the value decreases over time in a linear manner. Suppose that two years after purchase, an industrial milling machine is worth $830,000, and five years after purchase, the machine is worth $500,000. Find a formula for the machine value V (in thousands of dollars) at time t ≥ 0 after purchase. 2. Relevant equations v=? 3. The attempt at a solution This is what I got; At T=2 V=830,000 At T=5 V=500,000 V-500,000 =[T-5][500,000-800,000]/[5-2] C-500,000=[T-5][330,000] Is that right?
