If an 18 year old has $10,000 and that person puts that money into a savings plan that pays an annual interest rate of 5%, according to our textbook, at age 65 that $10,000 will have grown to

The amount at the age of 65 years will be $99059.71

Explanation:

We have given principle amount P = $10000

Rate of interest r = 5% = 0.05

Time t = 65 - 18 = 47 years

So time period n = 47

We have to find the amount after 47 years

Future value is given by

So the amount at the age of 65 years will be $99059.71

all of them make sense but, i would have to say ask someone who has been there/or lives there, and/or read recent newspapers from that city.

hope this !
