$1.$ Davis Inc. is considering buying a new machine for $$5$ million. This would replace an old machine that they had bought five years ago for $$4$ million.

If Davis decides to buy the new machine and replace the old one, what is the change in capital expenditure for the investment? Davis$$ tax rate is $25\%.$ Show your work
