Answer 1

`\boxed{\textsf {\textbf{The amount returned by the shopkeeper is \$ 50 - x .}}}`

Explanation:

Given that I buy a video game and pay $ 50 to the shopkeeper . And we need to find the expression how much change should I receive .

So , let us take that the video game costs x . There can be two cases .

★ Case 1 :-

When the cost of the product is same as the amount given . When the cost of the video game is $50 then the shopkeeper will give us no change .

`\boxed{\red{\sf Returned\ change = \$ 0 }}`

`\rule{200}2`

★ Case 2 :-

When the cost of the video game is less than $50 then the shopkeeper will return us some change that is equal to the difference if the amount given to shopkeeper and the cost of the video game .

If the cost of the video game is x , then the amount given to us by the the shopkeeper will be ,

`\boxed{\red{\sf Returned\ change = \$ 50 - x }}`
