a) What is the depreciation rate for a $50,000 BMW that is worth $28,000 after 5 years? (I already found the answer to this: 10.95%)

b) Write V as a function of r (Help me answer this part!)

Thank you!

**Damon**, Thursday, November 22, 2012 at 7:46pm(V/50,000)^(1/5) = 1-r

V/50,000 = (1-r)^5

V = 50,000 (1-r)^5

r = 1 - (28/50)^.2

= 1 - .56^.2

= 1 - .89

= .1095 or 10.95%
