1 Math 1313 Section 1.5a 1SECTION 1.5a Linear Functions and Math Models Simple Depreciation: Example 1: In 2001, the B&C Company installed a new machine in one of its factories at a cost of $250,000. The machine is depreciated linearly over 10 years with no scrap value. a. Find the rate of depreciation for this machine. b. Find an expression for the machine’s book value in the t-th year of use (0≤t≤10). c. If the machine was purchased in 2001, find the value of the machine in 2006. Example 2: A company’s car has an original value of $45, 000 and will be depreciated linearly over 5 years with scrap value of $5,000. a. Find the expression giving the book value of the car at the end of year t (0≤t≤5).
