4. The National Dog Food Corp. wants to mix 5000lb of special dog food. There are two principal ingredients in the mixture, both sources of protein, x1 and x2. The first source of protein which is x1 is Php30/lb and the second, x2, costs Php60/lb. Chemical constraints dictate that the mixture contains not more than 4000lb of x1l and must contain at least 2000lb of x2. How many pounds of each ingredient must be utilized in order to minimize the cost?
