Ms. Jones is making a blue and yellow rectangular mosaic on her wall. She wants to use 14 rows of tiles, with 24 tiles in each row. If she has 207 yellow tiles, how many blue tiles will she need to complete her design?

Answer 1

First, we need to find the total number of tiles Ms. Jones will need to complete her design. Since there are 14 rows of tiles, with 24 tiles in each row, the total number of tiles needed is 14 rows x 24 tiles per row = 336 tiles.

Since Ms. Jones already has 207 yellow tiles, we can subtract this number from the total number of tiles needed to find out how many blue tiles she will need: 336 tiles - 207 yellow tiles = 129 blue tiles.

Therefore, Ms. Jones will need 129 blue tiles to complete her design.
