A sum of money is deposited in a bank which offers a simple interest rate of 0.325% per annum. At
frosja888 [35]

Answer:

50.000

Step-by-step explanation:

the formula to get ther is the following:

X + ( X * \frac{0.325}{100} * 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 * \frac{0.325}{100}) and you multiply it by four.

All this added to your initial amount will be the final number you have 50.560
