A new motorboat costs $6000. The value of the boat decreases by 15% each year. What is the value of the boat after 3 years?

Elodia [21]

Answer:

The value of the boat after 3 years is $\$3,684.75$

Step-by-step explanation:

we know that

The formula to calculate the depreciated value is equal to

$V=P(1-r)^{x}$

where

V is the depreciated value

P is the original value

r is the rate of depreciation in decimal

x is Number of Time Periods

in this problem we have

$P=\$6,000\\r=15\%=15/100=0.15\\x=3\ years$

substitute

$V=6,000(1-0.15)^{3}$

$V=6,000(0.85)^{3}$

$V=\$3,684.75$
