Question: Purchasing equipment for 200000 for new store. Assuming the store has no other expenses or revenues other than those associated with this project. You are going to purchase an additional 12500 of inventory for production with the new equipment and set up a cash account with a balance of 2000. The purchase of inventory will result in an accounts payable of 4500. The firm's tax rate is 20percent. What is the net cash flow at time zero?

So far, I have this as my answer, but I am second-guessing myself. What have I done correctly or incorrectly?

-200,000-(12,500+2,000)=-210,000

-210,000+4,500=-205,000

Adding the AP seems like it may be wrong?
