find the length of each person's sandwich?
an 18inch long sandwich was purchased &
Jenny cuts the sandwich so that Demi gets 1/2 of what Jenny gets and Joel gets 3/4 of what Jenny gets.

  1. Damon

    de = .5 je
    jo .75 je

    je + de + jo = 18

    1 je + .5 je + .75 je = 18
    2.25 je = 18
    je = 8
    then
    de = 4
    and
    jo = 6
