Answer:
Ryan deposits $775 in an account that pays 4.24% simple interest for four years.
Brian deposits $775 in an account that pays 4.24% simple interest for one year.
A:
SI formula is : p x r x t
So, Ryan's interest after 4 years will be =
= $131.44
B:
Ryan's balance after 4 years will be =
= $906.44
C:
Interest earned after 1 year =

D:
Ryan's account earned $32.86 in the fourth year.
E:
Brian's interest after first year =
= $32.86
F:
Brian's balance after first year will be =
= $807.86
G:
Now p will be 807.86
So, interest after 1 year will be =
= 34.25
H:
After 2 years Ryan will have earned = dollars in interest.
And after 2 years, Brian will have earned = dollars in interest.
So, Brian earned more because in the second year his principle increased and Ryan's principle was same.
