a)$12180.53
b)A=P(1-r)^n
Step-by-step explanation:
The formula for depreciation to use is this case is;
A=P(1-r)^n
where
A=value of boat after 5 years
P=current value of boat = $45000
r=rate of depreciation= 23% =0.23
n=time span after the boat was boat= 5 yrs
Applying the formula
A=$45000(1-0.23)^5
A=$45000(0.77)^5
A=$12180.53
