So part A. It wants you to see the increasing and decreasing changes.

Answer 30

I have this for that part: Based on the information given in the table, you can see that the price on product A is decreasing. To find by how much the product price is decreasing, I need to subtract 0.82 by 1. 1 - 0.82 = 0.18 Based on that, you can see that the product is decreasing by 18%.
