Aiden is trying to save money and has $1800 to set aside in some type of savings account. He checked his bank one day, and found that the rate for a 12-month CD had an annual percentage yield of 4.25%. The interest rate on his savings account was 2.75% annual percentage yield. How much more simple interest wpuld Aiden earn if he invested in a CD for 12 months rather than leaving the $1800 in a regular savings account?
