Answer:
Explanation:
1. First calculate the value of a constant annuity of $1,500 for 15 years at the 8% return.
The formula is:
[tex]PV=C[\dfrac{1}{r}-\dfrac{1}{r(1+r)^t}][/tex]
Where:
Substitute and compute:
[tex]PV=\$ 1,500[\dfrac{1}{(0.08/12)}-\dfrac{1}{(0.08/12)(1+0.08/12)^{180}}][/tex]
[tex]PV=\$ 156,960.89[/tex]
2. Discount to the present year.
You calculate the value of the annuity 20 years from now.
Then, you must discount that value at the same 8% rate to have the price today.
[tex]Price=(Value\text{ }in\text{ }20\text{ }years)/(1+r)^t[/tex]
Here, the value in 20 years is $156,960.89, r = 0.08/12, and t = 240 (20 × 12).
[tex]Price=\$ 156,960.89/(1+0.08/12)^{240}=\$ 31,858.57[/tex]
