Provide with an excel table the calculation:

Stage $2$ of a decision tree shows that if a project is successful, the payoff will be $$62,000$ with a $50\%$ chance of occurrence. There is also the $50\%$ chance of a $-$$$8,000$ payoff. The cost of getting to Stage $2(1$ year out$)$ is $$20,000.$ The cost of capital is $13$ percent. What is the NPV of the project at Stage $1?$
