You make two savings bank deposits, $4,000 today, and $2,400 in 2 years time. Your bank pays an interest rate of 2%. What will your balance be (from these two deposits only) after 5 years (3 years after your second deposit)?

Answer should be a number given as a %. That is, for example 3.18% should be answered as 3.18 rather than 3.18% or 0.0318
