Find the difference in financial gains when $3,200 is invested for 8 years with an interest rate of 4.5% for both simple interest and compound interest, and interest is compounded annually.

$47,810.80

$231.57

$198.72

$1,350.72

To find the difference in financial gains between simple interest and compound interest, we can use the formula for simple interest:

Simple Interest = Principal * Rate * Time

For simple interest:
Principal = $3,200
Rate = 4.5% = 0.045 (as a decimal)
Time = 8 years

Simple Interest = $3,200 * 0.045 * 8 = $1,152

To find the compound interest, we can use the formula:

Compound Interest = Principal * (1 + Rate)^Time

For compound interest:
Principal = $3,200
Rate = 4.5% = 0.045 (as a decimal)
Time = 8 years

Compound Interest = $3,200 * (1 + 0.045)^8 = $4,560.72

The difference in financial gains between simple interest and compound interest is calculated by subtracting the simple interest from the compound interest:

Difference = Compound Interest - Simple Interest

Difference = $4,560.72 - $1,152 = $3,408.72

Therefore, the difference in financial gains is $3,408.72, which is closest to $3,400.72 in the given options. None of the provided answer choices are correct.
