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

Step-by-step explanation:

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

Let represent the original price of the product and 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:

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

where

is the sale price of the product

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

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.
