Anna inherits $70000 and decides to invest part of it in an education account for her daughter and the rest in a 5 year cd. if the amount she puts in the education account is $10000 more than three times the amount she puts in the cd, how much money does anna invest in each account?

E = amount she put for Education

CD = amount she put for a Certificate of Deposit.

so, whatever those amounts are, we know that all she got is 70,000 bucks total, so E + CD = 70000.

how much is three times the CD?  well, 3*CD or 3CD.

how much is 10,000 more than that?  well 3CD + 10000.

since we know that the amount on Education was 10000 more than three times the CD, then E = 3CD + 10000.



how much was it invested in the CD?  well, CD = 70000 - E.

The answer should be 5.
