Chairs need to be set up for the audience members. You want to use the fewest number of chairs and still meet these three additional conditions.

• There are 21 rows of chairs.

There are the same number of chairs in each row.

• There are an even number of chairs in each row.

Based on the 352 (88%) expected to attend, design a plan to set

up the chairs. State how many total chairs there are, and explain why your

plan meets these conditions.
