jacks dad is tiling his shower.on one wall, he will use 9 rows of 14 tiles. the 4 center tiles in the top 2 rows will have a special design on them. how many of the tiles will not have a design on them?

To find the number of tiles that will not have a design on them, we first need to determine the total number of tiles.

Jack's dad is using 9 rows of tiles on one wall. Each row has 14 tiles. So, the total number of tiles on that wall is:

9 rows x 14 tiles per row = 126 tiles

Now, we need to subtract the 4 center tiles in the top 2 rows that have a special design.

In each of the top 2 rows, there are 4 tiles with a special design. So, the total number of tiles with a special design on them is:

2 rows x 4 tiles per row = 8 tiles

To find the number of tiles that do not have a design, subtract the number of tiles with a special design from the total number of tiles:

Total number of tiles - Number of tiles with a design = Number of tiles without a design
126 tiles - 8 tiles = 118 tiles

Therefore, there will be 118 tiles without a design on them.
