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

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

Which is the required equation.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=
