A carpenter agrees to work under the conditions that he is to be paid $5.50 every day he works, but must pay $6.60 every day he does not work. At the end of 30 days he finds he has paid out as much as he has received. How may days did he work?

  • Math - ,

    5.5x = 6.6(30-x)
    I don't get an integer solution. Is there a typo?

  • Math - ,

    Let x = days worked
    Let 30 - x = days not worked, so
    $5.5 * x - $6.6 * (30 - x) = 0
    days worked = 16 and 4/11 days
    days not worked = 13 and 7/11 days.
    Goofy answers, as far as I'm concerned!
