The cost of each white tile was £2 the cost of each blue tile was 4 pounds work out the ratio of the total cost of the white tiles to the total of the blue tiles

2x/4y = x/2y = x : 2y

Step-by-step explanation:

The question only gave us the cost of each white tiles and blue tiles respectively. The cost of each white tiles is £2 while the cost of each blue tiles is £4. The total cost of the blue tiles and the white tiles can only be calculated if we know the number of blue and white tiles available.

Let us assume

the number of white tiles = x

the number of blue tiles = y

total cost of white tiles = 2 * x = 2x

total cost of blue tiles = 4 * y = 4y

Therefore, the ratio of the total cost of white tiles to the total cost of the blue tiles can be expressed as follows

2x/4y = x/2y = x : 2y

If the number of white and blue tiles is known it can be replaced in the ratio to find the ratio of the total cost of the white tiles to the total cost of the blue cost.
