Accepted Solution
A:
Answer:P(x) = 0.595xStep-by-step explanation:A store offers customers a a 30% discount on the price x of an item.Therefore, after 30% discount selling price of the item = [x - (30% of x)]= (x - 0.30x)= 0.70xThen the store takes off an additional 15% off on the same item then the final selling price of the given item will be = 0.70x - (15% of 0.70x)= (0.70x - 0.105x)= 0.595xAnd the function that represents the final selling price will be P(x) = 0.595x
