To find the amount of interest earned in one year, we can use the formula:
interest = principal * rate
Given that the principal (initial investment) is $700 and the yearly interest rate is 4.5% (which can also be written as 0.045), we can substitute these values into the formula:
interest = $700 * 0.045 = $31.50
Therefore, the amount of interest earned in one year is $31.50.
The correct answer is B. $31.50.
