Johnson?s Produce is purchasing fertilizer with two nutrients: N (nitrogen) and P (phosphorus). They need at least 180 units of N and 90 units of P. Their supplier has two brands of fertilizer for them to buy. Brand A costs $10 a bag and has 4 units of N and 1 unit of P. Brand B costs $5 a bag and has 1 unit of each nutrient. Johnson?s Produce can pay at most $800 for the fertilizer. How many bags of each brand should be purchased to minimize the cost? What is the minimum cost
