Problema Solution
Things did not go quite as planned. You invested $10,750.00, part of it in stock that paid 15% annual interest. However, the rest of the money suffered a 4.05% loss. If the total annual income from both investments was $1,489.00, how much was invested at each rate?

We can write:
.15n-.0405(10750-n)=1489
where 'n' is the amount invested in the 15% annual interest and '10750' is the amount in the 4.05% loss. Using Algebrator to solve for n, we get:
n=9622.15
Therefore
10750-n=1127.85
Therefore $9622.15 was put in the 15% annual interest and $1127.85 was in the 4.05% loss.
