Question 1135653
<br>
Re-post, making it clear what the problem is.<br>
(1) Are YOU putting the money in the CD, or is Tom?  If YOU are -- as the statement of the problem says -- then YOU earn whatever interest there is; Tom earns none.<br>
(2) The wording "5.5% interest per year" SUGGESTS simple interest rather than compound interest; but we don't know for sure.  Specify simple or compound interest.
