Finding actual price

  1. Nov 18, 2005 #1
    An 8 lbs. roast beef cost $2.79/lb. The edible portion is 65%. What is the actual price of the roast.?

    This is what i did

    1lb cost $2.79, so 8lbs cost $22.32. Am i correct, this will be the actual price right. What do i need to do with 65%. Please help.

    Of the 8 lbs of roast beef, only 65% or 0.65 is edible, the rest gets thrown away.

    So how much roast beef is one actually buying?
