Question 65072
A furniture manufacturing company manufactures tables and chairs. A table 
requires 8 labor-hours for assembly and 2 labor-hours for finishing. A 
chair requires 2 labor-hours for assembly and 1 labor-hour for finishing. 
The maximum labor-hours available per day for assembly and finishing are 
400 and 110, respectively. If x is the number of tables and y is the number 
of chairs produced per day, determine how many tables and chairs can be 
assembled and finished. 

Answer 

x = # of tables 
y = # of chairs 
Assembly: 8x+2y<=400
Finishing: 2x+y<=110
-----------
Rewrite each equation in slope-intercept form:
y<=-4x+200
y<=-2x+110
{{{graph(600,400,-10,50,-5,210,-4x+200,-2x+110)}}}
--------------
Find the intersection of the two lines:
-4x+200=-2x+110
2x=90
x=45
Solve for y as follows:
y=-2(45)+110
y=20
------------
Manufacture 45 tables and 20 chairs.
