Eva invested a certain amount of money at 5% interest and $1500 more than that amount at 17%. Her total yearly interest was $750. How much did she invest at each rate?

Answer 1

amount invested at 5% --- x
amount invested at 17% ---- x+1500

.05x + .17(x+1500) = 750
times 100
5x + 17(x+1500) = 45000
etc.

can you please let us know where we can invest at 17% ?
