Question

You are contemplating investing $50,000 between two different investments. One of the investments, a stable one, returns 5% annually. A more risky one returns 9% annually. You need a return of at least 7.5%. what is the maximum amount of the money that you can invest at the 5% rate?

Answer 4

I guess one way to solve this is let X = amount at 5%, P=$50,000, so (P-X) = amount invested at 9%.
You want X(1.05) + (P-X)(1.09) = P(1.075)
Simplify and solve for X, and I think that'll work.
