A source of endless confusion for many algebra students is the dreaded mixture problem. These are the problems that ask you things like, if you mix 10 bs of peanuts costing $1.50 per pound with cashews costing $2.50 per pound, how many pounds of cashews would you need to add so that the resulting mixture has a cost per pound of $1.95 ? Or, if you mix 10 liters of pure water with 15 liters of a 30% alcohol solution, what is the concentration of the resulting mixture? There are different way to approach mixture problems. However, essentially all mixture problems are exactly the same if we use the proper setup. For this discussion you will need to do the following: 1. Create your own mixture problem, do not use the above examples. 2. Solve ONE problem posted by another student, DO NOT solve more than one. 3. Comment on another students post, feel free to provide constructive comments, guidance, or an alternate perspective. 4. Solved your mixture problem. Post your solution AFTER someone has attempted your problem, or by Monday evening. Discuss what you if anything that you did differently Helpful Resources Check out the 3 Step Process c ∗
