Dominick, we know that 4% of 75000 is 75000(.04) = 3000. If we add the 3000 to 75000, we now have 104% of 75000.
The next year, we'll find 4% of 78000 and add it on, etc. It's going to look something like 75000(1.04)(1.04)...
Thus our formula.
V = 75000(1 + .04)3
Plug that into your calculator for an answer.
