Answer:
50.000
Step-by-step explanation:
the formula to get ther is the following:
X + ( X * * 4 ) = 50.650
X is the initial amount of money you need to find
4 are the years of interests
So, If you have interests, it means that some money will be added to yours. But how much?
The problem says that every year 0.325% of your initial amount will be added, so you will calculate that amount( X * ) and you multiply it by four.
All this added to your initial amount will be the final number you have 50.560
