Question

Things did not go quite as planned. You invested ​$21360​, part of it in a stock that paid​ 12% annual interest.​ However, the rest of the money suffered a​ 5% loss. If the total annual income from both investments was ​$​, how much was invested at each​ rate? How much money was invested at​ 12% annual​ interest?

Answer 1

1992

Explanation:

Let x be the amount invested at 12%.

Then the rest amount is (21360-x) dollars.

The 12% stock earning is 0.12x dollars.

The rest amount loss is 0.05*(21360-x) dollars.

Your equation is

interest - loss = total interest, or

0.12x - 0.05*(21360-x) = 1992 dollars.

Simplify and solve for x.
