Question 31

A consequenceion system requires a unwandering absorb of $50,000. The fickle absorb per ace is $25 and the fruits per ace is projected to be $45.  Find the tame-level subject-matter.

Question 32

Tracksaws, Inc. makes tractors and lawn mowers. The fixed makes a acquisition of $30 on each tractor and $30 on each lawn mower, and they retail all they can consequence. The season modifications in the deed provision, counterfeit, and tractor parterre are absorbed in the opineation.

Formulation:

Let                   x = enumerate of tractors consequenced per continuance

                       y = enumerate of lawn mowers consequenced per continuance

MAX 30x + 30y

subject to   2 x + y       ≤ 60

                 2 x + 3y     ≤ 120

                    x ≤ 45

                   x, y  ≥ 0
