Question

A group of students went to their favorite restaurant after the football game one Friday night. They all ordered from the menu and forgot to tell the server to give them separate checks. The bill totaled $27, including the tip. They decided to split the bill evenly, and they figured out how much each of them owed. But then three people said they had no money. The rest of the people had to chip in 45 cents extra to cover the tab.
HOW MANY PEOPLE WERE IN THE GROUP?

Provide an explanation and a diagram, if necessary.
They split the bill evenly. Three did not pay and that equalled 45cents (.45)
.45/3=.15, so .15x 180 people equals $27.
