4 families 27 participants 3 more chairs

Question

Four families each brought the same number of chairs to a block party. Three more chairs are needed to seat all 27 of the participants. How many chairs did each family bring?

Answer 1

"Four families each brought the same number of chairs"      Let x= number of chairs each family brought

 

"Four families each brought the same number of chairs to a block party. Three more chairs are needed to seat all 27 of the participants"   means        4x + 3 = 27

 

       4x = 24          [subtract 3 from both sides]

         x = 6             [divide both sides by 4]

 

"How many chairs did each family bring?"        Each family brought 6 chairs

 

Check:

      Is   4*6 + 3 = 27   ?

             24 + 3 = 27   ?

                 27 = 27   ?yes
