Answer:
The answer is b)$51.77.
Explanation:
The upper bound of future price is equal to the future value of:
- The current price of silver compounded continuously for one-year ( that is, one period); plus
- The future value of the storing cost compounded continuously for 0.25 year ( that is, 3 months calculated as 12 months minus 9 months).
Thus, upper bound of future price is calculated as below:
45 x e^12% + 1 x e^[12% x(3/12)] = 50.737 + 1.030 = $51.77 ( round to 2 decimal places).
So, the answer is b) $51.77.
