You're managing a project to install $200$ windows in a new skyscraper and need to figure out your budget. Each week of the project costs the same: your team members are paid a total of $$4,000$ every week, and you need $$1,000$ worth of parts each week to do the work. The project is scheduled to last $16$ weeks.

You've checked with your team, but they have bad news. The schedule says they were supposed to have installed $50$ windows by now, but they've only installed $40.$ What is the actual $\%$ complete? Do not include $\%$ sign symbol.
