A person weighed themselves at 180 lb. Three months later they weighed themselves at 160 lb. Which of the following is the percent of weight the person lost over 3 months? (Round to the nearest percent.)<\/p>\n\n\n\n

A.
20%<\/p>\n\n\n\n

To find the percentage of weight lost, use the following formula:Percent Weight Loss=(Initial Weight\u2212Final WeightInitial Weight)\u00d7100\\text{Percent Weight Loss} = \\left( \\frac{\\text{Initial Weight} – \\text{Final Weight}}{\\text{Initial Weight}} \\right) \\times 100Percent Weight Loss=(Initial WeightInitial Weight\u2212Final Weight\u200b)\u00d7100<\/p>\n\n\n\n

    \n
  1. Identify the weights:<\/strong>\n
      \n
    • Initial Weight = 180 lb<\/li>\n\n\n\n
    • Final Weight = 160 lb<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Calculate the weight lost:<\/strong>Weight\u00a0Lost=180\u2212160=20\u00a0lb\\text{Weight Lost} = 180 – 160 = 20 \\text{ lb}Weight\u00a0Lost=180\u2212160=20\u00a0lb<\/li>\n\n\n\n
    • Calculate the percentage of weight lost:<\/strong>Percent\u00a0Weight\u00a0Loss=(20180)\u00d7100\\text{Percent Weight Loss} = \\left( \\frac{20}{180} \\right) \\times 100Percent\u00a0Weight\u00a0Loss=(18020\u200b)\u00d7100 Percent\u00a0Weight\u00a0Loss=20180\u22480.1111\\text{Percent Weight Loss} = \\frac{20}{180} \\approx 0.1111Percent\u00a0Weight\u00a0Loss=18020\u200b\u22480.1111 Percent\u00a0Weight\u00a0Loss\u22480.1111\u00d7100=11.11%\\text{Percent Weight Loss} \\approx 0.1111 \\times 100 = 11.11\\%Percent\u00a0Weight\u00a0Loss\u22480.1111\u00d7100=11.11%Rounding to the nearest percent gives 11%.<\/li>\n<\/ol>\n\n\n\n

      Therefore, the percent of weight lost over 3 months is:<\/p>\n\n\n\n
