Answer:

The function that represents the cost to mail a package if x is the number of ounces over 2 pounds is:


P(x)=0.30x+7

Explanation:

Let's asume we're already over 2 pounds. This means that we have to pay, at least, $7 for the first 2 pounds. Aditionally, we'll have to pay an extra 30 cents for each aditional ounce (x).

This way, the function that represents the cost to mail a package if x is the number of ounces over 2 pounds is:


P(x)=0.30x+7
