Yield response to several growth factors: This is a continuation of. If more than one nutrient is considered, the formula for percentage of maximum yield is a bit more complex. For three nutrients, the formula is

Here Y is the percentage of maximum yield as a decimal, b is the number of baules of the first nutrient, c is the number of baules of the second nutrient, and d is the number of baules of the third nutrient.

a. Express using functional notation the percentage of maximum yield produced from 1 baule of the first nutrient, 2 baules of the second nutrient, and 3 baules of the third nutrient, and then calculate that value.

b. One baule of nitrogen is 223 pounds per acre, 1 baule of phosphorus is 45 pounds per acre, and 1 baule of potassium is 76 pounds per acre. What percentage of maximum yield will be obtained from 200 pounds of nitrogen per acre, 100 pounds of phosphorus per acre, and 150 pounds of potassium per acre?
