In a graduation ceremony, each graduate can bring their 2 parents. Twenty teachers and half as many administrators will also attend the graduation ceremony. If there are 50 graduates, how many chairs must be prepared for the ceremony? Let's be accurate as possible.

There will be 50 x 2 = 100 parents that are expected to attend. 20 / 2 = 10 administrators will attend. Hence, 50 graduates + 100 parents + 20 teachers + 10 administrators = 180 chairs must be prepared.
The answer: 180.
