Quizplus · Accepted Answer

To find Jackie's weight, we first calculate the total weight of her sisters: 116 + 145 + 125 + 120 = 506 lb. Since Jackie and her sisters have an average weight of 131.9 lb, and there are 5 of them (Jackie + 4 sisters), the total weight for all 5 is 131.9 * 5 = 659.5 lb. Subtracting the sisters' total weight from this gives Jackie's weight: 659.5 - 506 = 153.5 lb.
