Printer

"Guess who bought the printer? That is the question."

Printer
The Printer is what print's papers for Emath. They use it to print homework, tests, report cards, etc. The manager bought the printer, but they did not use their own money, they used THE MONEY WE PAID. So the question of the answer is the money we paid. They put many papers inside because there are many students in Emath. The printers can staple papers for students. The managers are fine with it, only the printer can do things by themselves.

Why they used our money to buy the printer
The reason why is because the printer is too expensive and they wanted to use other people's money. That way, their life is a lot easier.
