Sam is tiling a floor. He%C2%A0will use the same repeating pattern for the entire floor. The rule is "Blue Tile, White Tile, Black Tile." If he uses 85 tiles, how many will be black? Enter your answer in the box.%C2%A0%C2%A0 %C2%A0 (1 point)
Since the pattern of the tiles is "Blue Tile, White Tile, Black Tile," it means that every three tiles, one of them will be black.
Therefore, we need to find how many groups of three tiles there are in 85 tiles.
85 divided by 3 equals 28 with a remainder of 1.
This means that there are 28 groups of three tiles, and there is one additional tile remaining.
So, there will be 28 black tiles.
