Question 1087766
 Diana inherits $45,000 and decides to invest part of it in an education account for her daughter and the rest in a 10-year CD.
 If the amount she puts in the education account is $12,000 more than twice the amount she puts in the CD, how much money does Diana invest in each account?
:
let x = amt invested in the CD
"the amount she puts in the education account is $12,000 more than twice the amount she puts in the CD,", therefore
2x + 12000 = amt invested in the ed acct
:
cd + ed acct = $45,000
x + (2x+12000) = 45000 
3x + 12000 = 45000
3x = 45000 - 12000
3x = 33000
x = 33000/3
x = $11,000 invested in the cd
then
2(11000) + 12000 = $34,000 invested in the ed acct
