Answer:
a) $515
b) $530.45
c) The amount grew faster in the second year. Because after each year, the amount she has increase, and then the 3% will be applied over a higher amount than before, generating more profit than the previous year.
Step-by-step explanation:
a)
After one year, the amount increased is 3% of the inicial value, so it is 0.03 * 500 = $15
So Sofia has 500 + 15 = $515 at the end of the year.
b)
After the second year, the amount will increase by 3%, but now the amount is 515, so we have 0.03 * 515 = $15.45
So Sofia has 515 + 15.45 = 530.45 at the end of the second year.
c)
The amount grew faster in the second year. Because after each year, the amount she has increase, and then the 3% will be applied over a higher amount than before, generating more profit than the previous year.
