Answer:
$38,771.44
To achieve at least the 8% rate Walt can pay until this amount.
Explanation:
The goal would be to calcualte the present value for each cashflow using the expected rate of 8%
[tex]\left[\begin{array}{ccc}-&Cash Flow&Discounted\\Year \: 1&12,500&11,574.0740740741\\Year \: 2&10,000&8,573.38820301783\\Year \: 3&7,500&5,953.74180765127\\Year \: 4&5,000&3,675.14926398227\\Year \: 5&2,500&1,701.45799258438\\Year \: 6&0&0\\Year \: 7&12,500&7,293.62994077667\\Total&50,000&38,771.4412820865\\\end{array}\right][/tex]
[tex]\frac{Principal}{(1 + rate)^{time} } = Present \: Value[/tex]
For example year 3
[tex]7,500\div \: 1.08^3 = 5953.74180765127[/tex]
Then we add each cashflow, to get the present value of the project.
