**False.**The length of each wall is 8 feet, meaning that the square footage of the floor is 8x8 or 64 square feet. Thus, she would need to purchase 8 packs of Trinoleum Tiles, costing $80 before the $10 rebate, so $70 total.**True.**Each wall requires 80 square feet of paint (8x10 dimensions per wall), so with four walls she will require 320 square feet of paint total. For two coats, then, she will require 640 square feet. At 32 square feet per can, then she will require 20 cans. 20 cans * $25/can = $500 before the $15 rebate.**True.**As discussed in the solution above, she will require 320 square feet of wall covering. Each pack of Cloud Wallpaper provides 80 square feet, so she will require 4 packs at $32 each. Therefore, she will spend $128 before the $35 rebate. Even without doing the pen-and-paper math to arrive at the after-rebate cost of $93, you should quickly be able to note that $128 less a $35 rebate will be less than $100, so the statement is true.**False.**Before the rebate, the costs are the same. To cover her floor, she needs to cover 64 square feet (8 feet x 8 feet), so she will require 4 packs of Lavartine tiles at $15/each for a cost of $60. To cover her walls, she will need a total of 320 square feet (4 walls * 8x10 feet per wall), and will therefore require two packs of Rainbow Wallpaper at $30/pack. The pre-rebate cost is thus $60, as well. Only after the $20 rebate on wallpaper and $10 rebate on tile does the cost difference become realized.**True.**Wall coverings will require her to purchase 320 square feet's worth, which requires 10 cans of paint at $25/can. That $250 figure is much higher than wallpapering ($60 pre-rebate with Rainbow, the cheaper option) or tiling ($60 pre-rebate with Lavartine, the cheaper option). And because the paint rebate is only $15, one need not do the math to recognize that paint is by far the most expensive option and will not come close to the potential for tile/wallpaper together.
