Answer:

38.84

Explanation:

19 L of petrol cost £24.70

We can write this proportion as:

19 L / £24.70 = 30 L / x

Where x represents the cost of 30 L of petrol.

To solve for x, we can cross multiply and then divide:

(19 L)(x) = (30 L)(£24.70)

19x = 30 * 24.70

Now, we can solve for x:

x = (30 * 24.70) / 19

x ≈ £38.84

Therefore, 30 L of petrol will cost approximately £38.84.
