Find \( r \) if

\[ 2700 = 2200(1+r)^5 \]

(Note: \( ^5 \) is the exponent for 5)

2700 = 2200 ( 1 + r ) 5 / : 2200 ( 1 + r ) 5 = 22 27 ​ 1 + r = 5 22 27 ​ ​ r = 5 22 27 ​ ​ − 1

To find r in the equation 2700 = 2200 ( 1 + r ) 5 , isolate the term to get ( 1 + r ) 5 = 22 27 ​ . Taking the fifth root gives 1 + r , then subtracting 1 results in r ≈ 0.0455 or 4.55%.
