Question

describe a real life situation involving markup, markdown, or discount that the equation y=x +0.4 could represent

Answer 1

Suppose the cost price of an article is increased by $ 0.4. What will be the marked price of the article ?

Solution :

Consider the cost price of the article is x,

Mark up = $ 0.4,

Therefore, the marked price( say y ) = cost price + mark up

`\implies y = x + 0.4`

Which is the required equation.
