emily kailyn received an inheritance of $208,000.00 from her grandfather and invested part at 10% interest and the rest at 4% interest. She earned $9,160.00 interest each year on his investment. How much did she invest at 4%?

Step 1

Follow below steps to obtain the answer: -

As we know that formula for calculating simple interest is as below: -

Simple interest on a sum of principal, P is S.I. = (P*R*t)/100

Where ‘R’ is rate of interest.

And ‘t’ is the time.

Let us consider that Emily Kailyn invested an ‘*x*’ amount of inherited money to a 10% interest.

So, the remaining money she has is equals to $208,000.00 –* x *which she invested at an interest of 4%.

Thus, we can calculate the amount she earned as simple interest after one year as below: -

Step 2

It has been given to us that the amount she earned is equal to $9,160.00

Now, solve the equation (1) by substituting the value of amount earned equals to $9,160.00 and solve as below: -

Step 3

Now, we can calculate the amount she inve...
