Southern Bank has two types of account.
Both accounts pay compound interest.
Everyday saver account:
Interest
2.4% per annum
1234 account:
Interest
3.4% per annum
Sue invests £2300 in the saver account.
Bill invests £1800 in the 1234 account.

Bill:
b) If the interest for the 1234 account changes to 4% in the 3rd year,
who will get the most interest after 3 years, Sue or Bill?
