With simple interest at 6.5%, the interest earned can be calculated using the formula: Interest = Principal * Rate * Time
where Principal is $6,700, Rate is 6.5%, and Time is 3 years.
Interest earned with simple interest = $6,700 * 0.065 * 3 = $1,304.50
With compound interest at 6%, the interest earned can be calculated using the formula: Amount = Principal * (1 + Rate/100)^Time
where Principal is $6,700, Rate is 6%, and Time is 3 years.
Amount with compound interest = $6,700 * (1 + 0.06)^3 = $7,620.09
Interest earned with compound interest = Amount - Principal = $7,620.09 - $6,700 = $920.09
Now, we can find the difference between the two interest earnings:
Difference = Interest earned with compound interest - Interest earned with simple interest
= $920.09 - $1,304.50 = -$384.41
Since the difference is negative (-$384.41), it means that the interest earned with simple interest is higher than with compound interest. Therefore, Aria should invest with 6.5% simple interest because it will result in $384.41 more in interest earnings.
So, the correct answer is: Aria should invest with 6.5% simple interest because it will result in $384.41 more in interest earnings.
