A chair company produces two models of chairs. The Sequoia model takes 3 worker-hours to assemble and worker-hour to paint. The Saratoga model takes 2 worker-hours to assemble and I worker-hour to paint. The maximum number of worker-hours available to assemble chairs is 240 per day, and the maximum number of worker-hours available to paint chairs is 80 per day. Write a system of linear inequalities to describe the situation. Let x represent the number of Sequoia models produced in a day and y represent the number of Saratoga models produced in a day. Find the region described by this system of linear inequalities.
Since negative numbers of chairs cannot be produced, x≥ 0 and y ≥0. The inequality for assembly time is 3x + 2y ≤ 240. The inequality
for painting time is -1/2x+y≤80. The system of
inequalities is
[3x+2y≤240,
1/2x+y≤80,
x>=0
y>=0
The region consists of points on or above the x-axis and on or to the right of the y-axis. In addition, the points must be on or below the line 3x+2y= 240 and on or below the line
1/2 x+y=80 (or, equivalently x + 2y = 160).
