Answer and Explanation:
The computation is shown below:
1. In the case when the rate of interest is 6%
So, the present value is
1. For at the end of eight years, the present value of $7,000 is
= $7,000 × 6.20979
= $434,68.53 or $43,469
2. The lumpsum now is $45,000
3. The eight years from now is
= $75,000 × 0.62741
= $47,00,55.75 or $47,056
Thus, the highest present value = $47,056
2. In the case when the rate of interest is 12%
1. For at the end of eight years, the present value of $7,000 is
= $7,000 × 4.96764
= $34,773.48 or $34,773
2. The lumpsum now is $45,000
3. The eight years from now is
= $75,000 × 0.40388
= $30,291
Thus, the highest present value = $45,000
