Question

Carlos has 2 dollars more than half of the total amount of money his brother has. If x represents the amount of money Carlos's brother has, which expression can be used to represent this situation?

Answer 1

`y = 2 + (1)/(2)x`

Explanation:

Given

Represent Carlos with y and his brother with x.

Analysing the statement one after the other:

Half of his brother's amount is:
`(1)/(2)x`

$2 more: means we add 2 to
`(1)/(2)x`

So, we have:
`2 + (1)/(2)x`

The above represent Carlos's amount.

So, the expression is:

`y = 2 + (1)/(2)x`
