The equation you use is:
final value = initial value * (rate of depreciation) ^ time
1000 = 15000(x)^10
x = .762765 or 76.2765%
value after 7 years is just:
15000(.762765)^7 = 2253.34
final value = initial value * (rate of depreciation) ^ time
1000 = 15000(x)^10
x = .762765 or 76.2765%
value after 7 years is just:
15000(.762765)^7 = 2253.34
