Answer 1

`C`

Step-by-step explanation:

Here, we want to get the expression that could be used to represent the cost of Benji's shoes

From the question, his shoes are 20% more worth than his brother

Mathematically, we have the cost as:

`\begin{gathered} \text{ x + 20\% of x} \\ =\text{ x + 0.2x = 1.2x} \end{gathered}`

we can see that both options A and B are correct
