Aria should invest with 6% compound interest because it will result in $86.76 more in interest earnings.
Aria should invest with 6.5% simple interest because it will result in $187.26 more in interest earnings.
Aria should invest with 6.5% simple interest because it will result in $26.69 more in interest earnings.
Aria should invest with 6% compound interest because it will result in $73.81 more in interest earnings.
To find the difference between the two interest earning types, we can use the formula for simple interest:
Simple Interest = Principal * Rate * Time
For simple interest at 6.5%, the interest earned would be:
Interest = 6700 * 0.065 * 3 = $1303.50
Now, let's calculate the compound interest using the formula:
Compound Interest = Principal * (1 + Rate)^Time - Principal
For compound interest at 6%, the interest earned would be:
Interest = 6700 * (1 + 0.06)^3 - 6700 = $1216.74
The difference between the two interest earnings is:
1303.50 - 1216.74 = $86.76
Therefore, Aria should invest with 6.5% simple interest because it will result in $86.76 more in interest earnings.
