There two types of fertilizers F1 and F2. F1 consists of 10% nitrogen and 6% phosphoric acid and F2 consists of 5% nitrogen and 10% phosphoric acid. After testing the soil nutrient composition, a farmer found that she needs at least 14kg of nitrogen and 14kg of phosphoric acid for her crop. If F1 costs 600 Tsh. Per kilogram (kg) and F2 costs 500 Tsh. per kilogram.
