If a store offers a 40 percent discount on all products, which linear model will help us find the sale price of a product?

Accepted Solution

Answer:[tex]y=0.6x[/tex]Step-by-step explanation:If the store is offering 40 percent discount, it means that is charging 60 percent of the original price. Let [tex]x[/tex] represent the original price of the product and [tex]y[/tex] 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:[tex]y=\frac{60}{100} x[/tex][tex]y=0.6x[/tex]We can conclude that the linear model that help us find the sale price of a product is [tex]y=0.6x[/tex]where [tex]y[/tex] is the sale price of the product [tex]x[/tex] is the price before discount (original price) of the product
