Answer:


y=0.6x

Explanation:

If the store is offering 40 percent discount, it means that is charging 60 percent of the original price.

Let
x represent the original price of the product and
y the sale price after discount.

Since the price after discount is 60 percent of the original price, y = 60%x

Now, to convert 60% percent to decimal (and complete our model), we just need to divide it by 100%, so:


y=(60)/(100) x


y=0.6x

We can conclude that the linear model that help us find the sale price of a product is
y=0.6x

where


y is the sale price of the product


x is the price before discount (original price) of the product
