Find the rate of depreciation to the nearest whole percent for the car in problem 19.

OpenStudy (anonymous):

Where is problem 19?

OpenStudy (anonymous):

oh sorry.. just a minute

OpenStudy (anonymous):

Problem 19 find the average annual deprectaion for a car that cost $19,000 three years ago and is now worth $12,100. I got $2,300 for this. :)

OpenStudy (anonymous):

Are you there? :)

OpenStudy (amistre64):

there are many methods of calculating depreciation, are we to assume a straight line method here?

OpenStudy (amistre64):

also, depreciation and worth (fair market value?) tend to be different concepts in accounting

OpenStudy (anonymous):

Im not sure.. this is consumer mathematics. Help please? :)

OpenStudy (amistre64):

if we assume that the worth is based upon a straightline depreciation method, then yes, the annual depreciation would amount to inital cost minus present worth, divided by 3 years gives me 2300 a year

OpenStudy (amistre64):

the rate of depreciation .....

OpenStudy (anonymous):

Ok then you would get 766.6?

OpenStudy (amistre64):

im not sure what its refering to by a percentage tho maybe depreciation value divided by initial cost? there should be a formula in your material that covers this

OpenStudy (amistre64):

or it might be the depreciation cost divided by the worth

OpenStudy (anonymous):

Hmm.. Well I have the answer in my book and it says 12%.. No idea how the got that..

OpenStudy (amistre64):

well, 2300/19000 = .12105 which would seem to be correct them

OpenStudy (amistre64):

it loses about 12% of its initial value each year

OpenStudy (anonymous):

So you take the answer from number (19) $2,300 and the divide it by the prive the car was three years ago and the you get .12105 and the round of and then get .12 = 12%

OpenStudy (amistre64):

yes
