To answer the question, I assume that the given interest is annual and simple interest. The interest acquired by the investment in simple interest is given by the equation,
I = P x i x n
where I is interest, P is present worth, i is rate and n is number of interest period. Assuming that a year is 360 days,
I = ($700) x (0.105) x (90/360)
The answer is 18.375. Therefore, the interest due is approximately equal to $18.38.
