Problema Solution
Deluxe coffee is to mixed with regular coffee to make at least 47 pounds of blended coffee. The mixture must contain at least 12 pounds of deluxe coffee. Deluxe coffee costs $5 per pound and regular coffee $4 per pound. How many pounds of each kind of coffee should be used to minimize costs?

To simply minimize costs and require "at least" 12 pounds of deluxe coffee, then 12 pounds of deluxe coffee is used (costs will always increase if more deluxe coffee is mixed in). That leaves 47-12=35 pounds of regular coffee.
The actual cost will be:
5*12+4*(47-12)
200
The blend would cost $200.
