 Question 489762: According to data from a Texas agricultural report, the amounts of nitrogen (lb/acre), phosphate (lb/acre) and labor (hr/acre) needed to grow honeydews, yellow onions, and lettuce are given by the following table: YELLOW HONEYDEW ONIONS LETTUCE NITROGEN 120 150 180 PHOSPHATE 180 80 80 LABOR 4.97 4.45 4.65 If a farmer has 220 acres, 29,100 pounds of nitrogen, 32,600 pounds of phosphate, and 1061 hours of labor available, can he use all of his resources completely? If so, how many acres should he allot for each crop? We set up the initial equations: 120H + 150Y + 180L = 29,100 180H + 80Y + 80L = 32,600 4.97H + 4.45Y + 4.65L = 1061 OR 497H + 445Y + 465L = 106,100 (easier than decimals) The instructor is working with systems of linear equations and matrices.
