Answer:
Assume the interest rate applied is 6%.
* The present value at time zero: $173,255;
* Corresponding future values at the end of year 7: $245,766.
Explanation:
* The present value at time zero:
Apply the formula for calculating present value of the annuity to come up with the present value of the annuity as at the end of Year 1:
(50,000/6%) * [ 1 - 1.06^(-4) ] = $173,255
Present value at time zero by discounting one more period = $173,255/1.06 = $163,448.
* Corresponding future values at the end of year 7:
Apply the formula for calculating future value of the annuity to come up with the future value of the annuity as at the end of Year 5:
(50,000/6%) * (1.06^4 -1) = $218,731
Future value at the end of Year 7 by compounding two more period = $218,731 * 1.06^2 = $245,766.
