1 admin is good to manage ???? computers

I currently have 35 computers and 3 servers I am responsible for in 2 separate locations. One location has 25 and the other 10. I have no problem handling this by myself currenly. Our company is looking to merge with another company with 200 computers. How many people should the IT team consist of? Should one person be able to handle 235 computers along with 8 servers?
