Johann has 3 sheets of wallpaper. each sheet of wallpaper has an area of 12 square feet. johann cuts the wallpaper into square foot pieces. how many pieces are there altogether?

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .

cross multiplying, we get :
