Answer:
Step-by-step explanation:
To calculate the interest earned from both accounts, we need to determine the interest earned from each account separately and then sum them up.
Let's calculate the interest earned from each account:
1. First Oak:
Principal amount = 1/2 * $1629.5 = $814.75
Interest rate = 6%
Time = 5 years
Interest earned from First Oak = Principal amount * Interest rate * Time
= $814.75 * 0.06 * 5
= $244.425
2. West United:
Principal amount = 1/2 * $1629.5 = $814.75
Interest rate = 5% compounded annually
Time = 5 years
Use the compound interest formula to calculate the interest earned from West United:
Interest earned from West United = Principal amount * (1 + Interest rate)^Time - Principal amount
= $814.75 * (1 + 0.05)^5 - $814.75
= $814.75 * (1.05)^5 - $814.75
= $814.75 * 1.27628 - $814.75
= $1041.36 - $814.75
= $226.61
Now, sum up the interest earned from both accounts:
Total interest earned = Interest earned from First Oak + Interest earned from West United
= $244.425 + $226.61
= $471.035
Therefore, Giovanna will have earned approximately $471.04 in interest from both accounts at the end of 5 years.
