Answer:
£13.5
£40.5
Step-by-step explanation:
Let the amount of shares be x and 3x
Therefore,
![x + 3x = 54 \\ \\ 4x = 54 \\ \\ x = \frac{54}{4} \\ \\ x = 13.5 \\ \\ 3x = 3 \times 13.5 = 40.5](https://tex.z-dn.net/?f=x%20%2B%203x%20%3D%2054%20%5C%5C%20%20%5C%5C%204x%20%3D%2054%20%5C%5C%20%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B54%7D%7B4%7D%20%20%5C%5C%20%20%5C%5C%20x%20%3D%2013.5%20%5C%5C%20%20%5C%5C%203x%20%3D%203%20%5Ctimes%2013.5%20%3D%2040.5)
I think the first one is correct. Since “three less than z squared” insinuate that the value is 3 units less than the value z^2
