Hello!
Judging on the question you have provided I have generated this equation to represent the situation 400(1.03^x) X being years.
To solve this equation you need to plug in 16 for X amount of years. 
The new equation should look something like this 400(1.03^16)
Lastly solve!
The answer you get should be $641.88
Hope this helped!
