Document Summary

Duration: 3 hours: [11 points] two chemical plants, plant a and plant b, produce three types of fer- tilizer: lp, mp and hp. At each plant, the fertilizer is produced in a single production run, so the three types are produced in xed proportions. Lp, 2 tons of mp and 3 tons of hp in a single production run, and charges for what was produced in one run. Plant b produces 1 ton of lp, 5 tons of mp and 1 ton of hp, and charges for what was produced in one run. What is the minimal cost? (to earn full points, your solution must include a neat labelled diagram and show all calculations and appropriate justi cation. : [8 points] let a = . Use row reduction to determine if a is invertible. Show all your work and indicate the row operations used: [7 points] let a = indicate the operations used.
