an investor invested a total of $1,700 in two mutual funds. One fund earned a 7% profit while the other earned a 4% profit. If the investor's total profit was $86, how much was invested in each mutual fund?

Question

anonymous · Answer

If $x$ is the amount invested at 7%, then $1700 - x$ is the amount invested at 4%, right?

Since the profit on the amount invested at 7% plus the profit on the amount invested at 4% is 86:

$$0.07(x) + 0.04(1700 - x) = 86$$

Does that make sense?  Can you take it from there?
