# Math Help - Depreciation help

1. ## Depreciation help

I just can't seem to get the answer right here, really infuriating!

'A machine depreciates by 7% p.a. Its price when new is £8000. Calculate its depreciated value after 5 years, depreciated monthly.'

Please can someone help in terms of the appropriate method to use?

depreciation rate per month ... $\frac{.07}{12}$

$V(t) = 8000 \left(1 - \frac{.07}{12}\right)^{60}$
