Splitting investments. Joan had $3,000 to invest. She invested part of it in an investment paying 8% and the remainder in an investment paying 10%. If the total income on three investments was $290, than how much did she invest at each rate?

amount invested at 8%  x
amount invested at 10%  3000x
.08x + .10(3000x) = 290
.08x + 300  .1x = 290
.02x = 10
x = 10/.02 = 500
so $500 invested at 8% and 2500 invested at 10%
