Lacie wants to paint her bedroom walls. she has to cover 1,162.5 square feet. about how many gallons of paint will she need?

I dont really know. you dont know how big the walls are and how far 1 gallon goes so figure how far 1 gallon goes and then divide it by the 1,162.5

We need the pictures of the graphs
