Betsy, a recent retiree, requires $6,000 per year in extra income. She has $70,000 to invest and can invest in Brated bonds paying 17% per year or in a CD paying 7% per year. How much money should be invested in each to realize exactly $6,000 in interest per year?
I do not know what to do for this.

ok, so Betsy invest part of her $70,000 in Brate bonds paying 17% per year
.17x
the rest of the $70,000 she invest in a CD paying 7% per year
.07(70000x)
totally she wants to get $6,000 per year
= 6000
putting this all together:
.17x + .07(70000x) = 6000
solve for x. that will give how much she invested in Brated bonds. plug that in 70000x to find how much she invested in a CD 
$11,000
