The amount of money after t years in simple interest is modeled by:

In which:
- r is the interest rate, as a decimal.
The interest earned is:

A bank loaned out $14000, in two parts, hence:

Part of it at the rate of 9% per year and the rest at 17% per year, hence:

The interest received in one year totaled $2000, hence:

Then:



Isolating
as a function of
, then we can replace on the equation for the first interest.



Then:






$13,872 was loaned at 9%.
