Answer:

5.36 percent

Explanation:

A=P(1+r/100)^n

where

A=future value

P=present value

r=rate of interest

n=time period.

Hence

35996=29208(1+r/100)^4

(35996/29208)^(1/4)=(1+r/100)

(1+r/100)=1.0536(Approx)

Hence r=(1.0536-1)*100=5.36%

Answer: 5.36%

Explanation:

The problem above could be solved by applying the formula which relates Present value, future value, rate and time of an annuity.

From the question ;

Last Year Average selling price = Future Value(FV) = $35,996

Price 4 years earlier = Present Value (PV) at the time = $29,208

Period(t) = 4 years

Rate(r) = r

FV = PV × (1 + r)^4

35996 = 29208 × (1 + r/100)^4

$29208 × (1+r/100)^4 = $35996

(1+r)^4 = $35996/$29208

(1+r)^4 = 1.23240208

(1 + r) = (1.23240208) ^0.25

1 + r = 1.053629946

r = 1.053629946 - 1

r = 0.053629946

r = 0.0536

r = 5.36%
