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

400 I do not get it!!!!!!!!!!!!!!!

To find the number of white tiles Ron needs, we first need to calculate the total number of tiles required to cover the countertop.

Since Ron wants to have 54 tiles in each row and there are 8 rows, the total number of tiles needed is:

54 tiles/row * 8 rows = 432 tiles

Next, we need to calculate the number of blue tiles Ron wants to place. Each group contains 4 blue tiles, and he wants to place 8 groups, so the total number of blue tiles is:

4 tiles/group * 8 groups = 32 blue tiles

Finally, to find the number of white tiles, we subtract the number of blue tiles from the total number of tiles:

Total tiles - Blue tiles = White tiles
432 tiles - 32 blue tiles = 400 white tiles

Therefore, Ron will need 400 white tiles.

Thx so much I appreciate it

hard :)

I dont get it at all
