1 answer:
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
interest rate of A = 2%
The interest rate of B is higher.

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