You can put this solution on YOUR website! Tim and Judy mix two kinds of feed for pedigreed dogs. They wish to make 54 pounds of feed worth $.28 per pound by mixing one kind worth $.24 per pound with another worth $.42 per pound. How many pounds of the cheaper kind should they use in the mix?
[first mixture] + [second mixture] = [total mixture]
Let x = pounds for cheaper kind of feed
[x0.24] + [x0.42] = [(0.28)(2x + 54)]
We now solve for x.
