Dalia is installing a tile floor in a rectangular room. Dalia has 152 tiles available to tile the room. If each row requires 9.5 tiles, and 19 tiles broke while Dalia is laying the floor, how many full rows of unbroken tile can she install before running out of tiles?Choose 1 answer:(A) 12(B) 14(C) 16(D) 18
Q. Dalia is installing a tile floor in a rectangular room. Dalia has 152 tiles available to tile the room. If each row requires 9.5 tiles, and 19 tiles broke while Dalia is laying the floor, how many full rows of unbroken tile can she install before running out of tiles?Choose 1 answer:(A) 12(B) 14(C) 16(D) 18
Calculate total tiles: Calculate the total number of tiles available after accounting for the broken tiles. 152 tiles available −19 broken tiles =133 tiles remaining.
Determine full rows: Determine how many full rows can be installed with the remaining tiles.Since each row requires 9.5 tiles, we divide the number of remaining tiles by the number of tiles per row.133 tiles remaining /9.5 tiles per row =14 rows.
Check whole number: Check if the number of rows is a whole number since we can only install full rows.14 is a whole number, so Dalia can install 14 full rows of unbroken tile.
