The value of a particular investment follows a pattern of exponential growth. You invested money in a money market account. The value of your investment *t* years after your initial investment is given by the exponential growth model A = 2600 e ^{0.08t }. By what percentage is the account increasing each year?

*Solution:-*

after t years investment is initial investment

2600 = 2600e ^{(0.08*t)}

from the equation

= 0.08

r = 8

So account is increasing each year by 8%
