Question four makes no sense. A pound contains 16 ounces which is the max amount of ounces. The question should have been, what price does he need to sell them at to make a 20% profit. The teacher should be fired for that screw up alone.
Well the trick is the answer is simply 16. Teacher trolled you.
Like I could find it funny if it went in on all different races but this just attacks inner city black criminal stereotypes. Like the names are straight out of a Lisa Lampanelli show.
Still, very inappropriate for school. This is something that would be better shared in the teacher's lounge
