To answer the problem, you must the formula in finding the interest and after that we will add it to the principal to get the future value.
The formula is: I = Prt
Interest = Principal x rate x time
= 200 x 0.062 x 6/12
= $6.2 is the interest for 6 six months.
Future Value = Principal + Interest
FV = 200 + 6.20
FV = $206.20 is the amount to be paid at the end of 6 months.
