1. The Rice Co. has determined the minimum requirements of the amount of certain chemicals to grow rice successfully.

Fertilizer 1 Fertilizer 2 Minimum Number
Chemical A 2 kilos 3kilos 18 kilos
Chemical B 4 kilos 2 kilos 20 kilos
Chemical C 1 kilo 8 kilos
Chemical A costs PHP7 per kilo, Chemical B costs PhP9 per kilo, and Chemical C costs PHP11 per kilo. Find the minimum cost.
2. A food nutritionist wants to supply at least 28 mg of protein and at most 33 mg of iron. The breakfast cereal Sunshine provides 4 mg of protein and 3 mg of iron per tbsp. The breakfast cereal Sunrise provides 4 mg of protein and 7 mg of iron per tbsp. How many tbsp of each cereal should the food nutritionist mix in each serving at the minimum cost if 1 tbsp. of Sunshine costs PHP1 and 1 tbsp. of Sunrise costs PHP1.50?

Bomb B requires 1, 5, 2 lbs. of D, E, and F respectively. Bomb C requires 6, 1, 4 lbs of D, E, and F respectively. Find the production schedule that will give the minimum cost of the explosive ingredients. Suppose explosive D costs PhP100 per lb., explosive E costs PhP500 per lb. and explosive F costs PhP300 per lb.
