If 24 metres of material cost £21.60, what would 40 metres of the same material cost?

1 answer

We can solve this problem using proportions.

Let's set up the proportion:

24 metres / £21.60 = 40 metres / x

where x is the cost of 40 metres of the same material.

To solve for x, we can cross-multiply:

24 metres * x = 40 metres * £21.60

Simplifying:

x = (40 metres * £21.60) / 24 metres

x = £36.00

Therefore, 40 metres of the same material would cost £36.00.
