Question 1196208
<br>
The solution from the other tutor shows a typical formal algebraic method for solving the problem.<br>
Here is a less formal method that can be used to solve any 2-part "mixture" problem like this.  This method is especially quick and easy if the numbers are "nice".<br>
The two funds separately returned profits of 1% and 5%; the overall profit was 4%.<br>
That 4% is 3/4 of the way from 1% to 5%.  (look at the three numbers 1, 4, and 5 on a number line to see that, if it helps.)<br>
That means 3/4 of the total was invested at the higher rate.<br>
Since 3/4 was invested at the higher rate, the $8000 invested at the lower rate was 1/4 of the total; that means 3/4 of the total (the amount invested at the higher rate) was 3($8000) = $24,000.<br>
ANSWER: $24,000<br>
