This is a repost, I'd suggest scrolling down the list of answers. I've answered this problem(but my answer for part B is wrong, but someone has corrected me)

Bill    1800 (1+.034)3     After 3 years

Sue   2300 (1+.024)3             Edit: this will be the amount in the account after 3 years....subtract original amounts to get interst earned !!

 

Bill's interst if rate changes   1800(1.034)2 (1.04)1  - 1800 = .....

Sue's interst was  2300(1.024)3 - 2300 =.....
