Ron is tiling a countertop. He needs to place 54 square tiles in each of 8 rows to cover the counter. He wants to randomly place 8 groups of four blue tiles each and have the rest of the tiles in white. How many white tiles will Ron need?
54 rows of 8 use 432 white tiles
8 groups of 4 blue tiles use 32 tiles
that leaves 432-32 = 400 white tiles
