To find the number of tiles needed, we need to find the area of the wall to be covered, which is 55 in. × 40 in. = 2,200 sq. in. Since each tile covers an area of 5 in. × 5 in. = 25 sq. in., we can divide the total area by the area of one tile to get the number of tiles needed: 2,200 ÷ 25 = 88 tiles. Therefore, the best choice is C: 88 tiles.
