    haha nvm!! :)

  • math - ,

    summing pounds: 7+6+8+7 = 28 pounds
    summing ounces: 2+10+5+9 = 26 ounces
    since 16 ounces = 1 pound,
    26 ounces = 26/16 = 1.625 pounds
    total wight = 28+1.625 = 29.625 pounds,,
    therefore, 30 is greater than 29.625,
    --> i think it's letter A

    haha alright. :)
