Playing around GeoGebraTube I came across this nice visualization of the coffee problem by Judah Schwartz. http://www.geogebratube.org/student/m243091 And it made me want to do a visualization of the problem. This sketch allows you to make a mix, and guess what the price should be. You might also try to make a mix to hit a certain price point. Can different mixes have the same price/pound?
