 Question 345984: A broker invested \$24,000 in two mutual fnds, one earning 9% annual interest and the other earning 10%. After 1 year, the combined interest income is \$2117. How much was invested at each rate?Answer by Fombitz(13828)   (Show Source): You can put this solution on YOUR website!Let be tha mount at 9%, the amount at 10%. Total amount invested: 1. Total interest received: 2. Multiply eq. 1 by (-10) and add to eq. 2, Something is wrong with your numbers because that amount is greater than the total invested amount. If the entire amount was invested at 10%, the interest would be \$2400. If the entire amount was invested at 9%, the interest would be \$2160. Your interest amount is outside of the possible range. Check your numbers and re-post.
