• Vitamins B and C are found in two different foods F1 and F2. One unit of food F1 contains 2 units of B and 3 units of vitamin C. one unit of food F2 contains 4 units of B and 2 units of vitamin C. one unit of food F1 and F2 costs $3 and $2.5 respectively. The minimum daily requirement (for a person) of vitamin B and C is 40 and 50 units respectively. Assuming that anything in excess of daily minimum requirement of vitamin B and C is not harmful. • Find out the optional mixture of food F1 and F2at the minimum cost which meets the daily minimum requirement of vitamins B and C.
