Answer:
Given that the garden show is moving into a bigger area. The new space has 935 square feet of space for displays. There are 8 different displays, and each display will need the same amount of space.
To get the number of square feet each dispaly will get, divide 935 by 8, the quotient will be the required number of square feet and the remainder will be space left over.
For 935 ÷ 8, quotient will be 116 and the remainder will be 7.
Thus, each display gets 116 square feet of space.
There are 7 square feet of space left over.
