An investment of 6000 was made one year ago.

Part of the investment was placed into an account paying s interest at 8%

The remainder of the investment was placed into an account paying s interest at 13%

After one year, you received a total of 710 in interest. How much was invested in each account?

##### Calculate Principal Amounts for each fund:

For Fund 1, we invest an unknown amount, let us call it x

For Fund 2, the remaining principal is 6000 - x

##### Calculate Interest Credit for Fund 1

Since Fund 1 credits interest using the simple interest method, we have 0.08x

##### Calculate Interest Credit for Fund 2

Since Fund 2 credits interest using the simple interest method, we have 0.13(6000 - x)

##### Set up a grid with fund details:

 Interest Paid Principal Interest Rate Fund 1 0.08x x 8% Fund 2 0.13(6000 - x) (6000 - x) 13% Total 710 6000 --

##### Calculate x from the grid:

Since both Interest paid columns add up to the total interest earned of 710, we set up an equation

0.08x + 0.13(6000 - x) = 710

0.08x + 780 - 0.13x = 710

780 - 0.05x = 710

##### Subtract 780 from each side:

780 - 780 - 0.05x = 710 - 780

-0.05x = -70

##### Divide each side by -0.05

 -0.05x -0.05
 =
 -70 -0.05

##### Cancelling the -0.05 on the left side, we get:

x = 1400 ← Fund 1 Investment

This means we should 6000 - 1400 = 4600 into Fund 2

1400 into Fund 1
4600 into Fund 2

1400 into Fund 1
4600 into Fund 2
##### How does the Split Fund Interest Calculator work?
Free Split Fund Interest Calculator - Given an initial principal amount, interest rate on Fund 1, interest rate on Fund 2, and a total interest paid, calculates the amount invested in each fund.
This calculator has 4 inputs.

### What 3 formulas are used for the Split Fund Interest Calculator?

Fund 1 investment is x
Fund 2 investment is T - x
Interest paid = Interest Rate * Investment
