Rental costs for office space have been going up at 94 per y
Rental costs for office space have been going up at 9.4% per year compounded annually for the past 8 years. If office space rent is now $29 per square foot per month, what were the rental rates 8 years ago?
Solution
Formula for Compound Interest :
Amount = Principal[ 1+r/100]^n
where r = rate of intersrest compounded annually ; n = no. of years
A = P[ 1+ 0.094]^8
29 = P(2.0518)
P = 29/2.0518 = $14.13
8 years ago rent was $14.13 per square foot per month
