Coco's coffee charges different prices based on the number of pounds purchased. The pricing scale is modeled by the function below, where w is the weight in pounds purchased. Orders placed directly through the Web site are discounted by 1/3, but a shipping fee of $2.50 is added. Write a pricing function for orders placed through the Web site.

Primavera, right?

To write a pricing function for orders placed through the Web site, we need to consider the pricing scale, the discount, and the shipping fee.

Let's assume that the pricing scale is defined by the function P(w), where w is the weight in pounds purchased. The pricing scale will give us the price for a certain weight.

If we want to apply a discount of 1/3 to orders placed through the Web site, we can multiply the original price by (1 - 1/3) = (2/3).

To account for the shipping fee of $2.50, we simply add it to the discounted price.

Putting it all together, the pricing function for orders placed through the Web site can be written as:

P_web(w) = (2/3) * P(w) + $2.50

Here, P_web(w) represents the price for a given weight w when ordering through the Web site. P(w) represents the price without any discounts or shipping fee.
