The Right Blend
Most of us can remember being subjected to word problems, whether it was a happy challenge or a moment contributing to a lifelong math anxiety. A coffee merchant has two types of coffee beans, one selling for $3 per pound and the other for $5 per pound. The beans are to be mixed to provide 100 pounds of a mixture selling for $4.18 per pound. How much of each type of coffee bean should be used to form 100 pounds of the mixture? Why do I need to know this? Who decided what the right blend is anyway?
