1)

A has a greater principal

2)

Principal of A is $500, the principal of B is $400, so A's principal is greater by $100

3)

Annual interest rate of A:

10/500 x 100

The interest rate of B is higher.

4) B's annual interest rate is 5% and A's annual interest rate is 2%, so B's is higher by 3%.

Hope this helps! Have a great Tuesday!
