I have a question about finance. I am trying to do the following with Toyota:

You will use the WACC as the discount rate to conduct capital budgeting analysis for a project that the firm is considering and then decide whether it should be accepted or not which is Building a new Building for $1 million. If you do not have a number you need, research it and state your assumptions that you used to get the missing number.

I have no idea where to start?
