Tile Ratio Problem Solution
The problem states that the ratio of red tiles to blue tiles is 3:5 and there are 12 more blue tiles than red tiles.
If we denote the number of red tiles as 3x and the number of blue tiles as 5x (where x is a common multiplier), the difference between the number of blue tiles and red tiles can be expressed as:
5x - 3x = 12
Solving for x:
2x = 12
x = 12 / 2
x = 6
Now, we can find the number of red tiles, which is 3 times x, or 3 * 6:
3 * 6 = 18
Therefore, there are 18 red tiles in the box, so the answer is A. 18.
