To compare Account A and Account B for Aerial's situation, we can calculate how much money she would have in each account after 4 years.
Account A
- Principal: $5,500.00
- Interest Rate: 5.5% per year
- Time: 4 years
Using the formula for simple interest \( I = P \times r \times t \):
\[ I_A = 5500 \times 0.055 \times 4 \]
Calculating that:
\[ I_A = 5500 \times 0.055 \times 4 = 5500 \times 0.22 = 1210 \]
Total amount in Account A after 4 years:
\[ Total_A = Principal + Interest = 5500 + 1210 = 6710 \]
Account B
- Principal: $5,500.00
- Interest Rate: 4.5% per year
- Time: 4 years
Calculating the interest for the first 3 years:
\[ I_B = 5500 \times 0.045 \times 3 \]
Calculating that:
\[ I_B = 5500 \times 0.045 \times 3 = 5500 \times 0.135 = 742.5 \]
Total amount after 3 years:
\[ Total_{B3} = 5500 + 742.5 = 6242.5 \]
Now, after the 3rd year, a bonus of $250 is added to the account. This bonus also earns interest for 1 additional year at the same rate (4.5%).
Calculating interest on the bonus for 1 year:
\[ I_{bonus} = 250 \times 0.045 \times 1 = 11.25 \]
Total amount after 4 years, including the bonus interest:
\[ Total_B = Total_{B3} + 250 + I_{bonus} = 6242.5 + 250 + 11.25 = 6503.75 \]
Conclusion
Now we can compare the two totals after 4 years:
- Account A: $6,710.00
- Account B: $6,503.75
Thus, Aerial should choose Account A, earning her $206.25 more.
So the answer for the drop-downs is: "Aerial is planning on leaving the money in the account for 4 years and then withdrawing all funds, then account A is the better choice earning her $206.25 more."
