The 1997 a value of an object was $5000. in 2012 , it was worth $9500. the annual percent growth has been constant. what is the annual percent growth?
a) 1.37%
b) 2.37%
c) 3.37%
d) 4.37%

D. 4.37 %

Explanation:

Around 1997 the value of the object was  $5000 . it later worth $9500 in the year 2012. The period in time from 1997 to 2012 is roughly 15 years. The amount increased by 9500 - 5000 = $4500.

The annual percentage growth is constant . That means the percentage growth for each year is constant. The annual percentage growth can be computed as follows:

f = final value

i = initial value

years difference = y

((f / i)∧ 1/y - 1) × 100

f = 9500

i = 5000

(9500/5000)∧ 1/15 - 1

(1.9)∧1/15 - 1

(1.9)∧ 0.06666667 - 1

1.0437189836  - 1 =  0.0437189836

convert to percentage

0.0437189836  × 100 = 4.3718983645

Annual percentage growth = 4.37 %

the third answer is correct.
