My students went on a field trip to purchase decorations for our classroom. They had $20 to spend. They wanted to purchase canvases-(c) that cost $5.00 each and wallpaper-(w) that cost $2.75 each.

Select the equation that matches the situation.

• $5.00c + $2.75w= $20.00

• $5.00w + $2.75c= $20.00

• $20.00cw+ $5.00= $2.75

• y=mx+b
