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(32388) (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.
