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 students 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.
