55.Samantha had 75 necklaces to sell. For the first week, there was only 57 necklace left => 75 – 57 = 18 Thus, 18 necklace were sold. Let’s solve for the percentage => 18 / 75 = 0.24 => 0.24 * 100 = 24% Thus for the first week she were able to sell 24% of the necklace. For the second week, there was only 38 necklace left. Now the remaining from first week is 57. => 57 – 38 = 19 => 19 / 57 = 0.33 => 0.33 * 100 = 33% Thus on the second week it decreased around 33%.
