A Correct answer
Explanation

Total marked price = (3 * 95) + 180 + 470 = 285 + 180 + 470 = 935. Discount = 187. Discount % = (187 / 935) * 100 = 20%.

AI explanation

First, find the total marked price by adding the costs: three novels at 95 each equals 285, plus the chemistry book at 180 and the dictionary at 470, giving a total of 935. Using the discount percentage formula, discount percentage equals discount divided by marked price multiplied by 100. This gives 187 divided by 935 multiplied by 100, which equals 20 percent.
