Answer:

Around $9.19

Explanation:

"1/4" basically means:

1/4 = 0.25

THus, we can say annnual interest rate is 5.25%

Converting to decimal, we have:

5.25/100 = 0.0525

To find annual interest, we have to multiply interest rate (0.0525) with principal amount (700), so annual interest would be:

700 * 0.0525 = $36.75

That would be earned in 1 year.

But the money is kept LESS than 1 year, 3 months to be exact. We know

3/12 = 1/4th year

So, 3 months is 1/4th of a year. So $36.75 in 1 year, 3 months would be 1/4th of that:


(1)/(4)*36.75=9.1875

Rounding to 2 decimal places, that would be around $9.19
