How would you solve this? Thank you for any help you can give.Answer by JenniferTutors(83)   (Show Source): You can put this solution on YOUR website!Here's how I worked this problem: 144 Chairs CPR (chairs per row)= 2R - 2 (R=row) (two less than twice the number of rows) Now, I factored 144 and noticed that I plugged the 9 into the the equation as 9 rows: Solve further: So, in there are 16 chairs per row and 9 rows, And those two number multiplied equal 144.
