1. FERTILIZER NUTRIENTS (Please Use Excel and show screenshots :) )
A produce farmer is purchasing fertilizer containing three nutrients: nitrogen, phosphorus, and potassium. The farmer’s minimum weekly requirements are 240 units of nitrogen, 120 units of phosphorus, and 80 units of potassium. There are two popular blends of fertilizer on the market. Blend A costs $8.00 a bag, and contains 4 units of nitrogen, 6 units of phosphorus, and 4 units of potassium. Blend B costs $10.00 a bag, and contains 12 units of nitrogen, 2 units of phosphorus, and 2 units of potassium.
(a) How many bags of each blend should the farmer purchase each week to minimize the cost of meeting the nutrient requirements?
(b) What is the minimum weekly cost?
