Question 970677
34  workers are available to assemble tables and chairs.
Note: That is a constraint
----------------------------------
it takes 5 people to assemble a table and 3 people to assemble a chair. the 
That gives you the following people Inequality::
5t + 3c <= 34 people
------
workers always make at least 4 chairs for every one table
That is a constraint:: c >= 4t
-------
what is the maximum total number of chairs and tables that can be made?
Find the constraints, equation to optimize and the maximum.
=======
Rearrange the 2 inequlities so you can graph them::
You graph in the 1st quadrant because c >= 0 and t is >= 0
c >= 4t
c <=(-5/3)t + (34/3)
----
Find the intersection of the borders:
Solve:
4t = (5/3)t + (34/3)
(7/3)t = (34/3)
7t = 34
-----
Comment:: I'm beginning to think the number of workers is 35, not 34.
If it is 35 you get:
t = 5 and c = 20 as one of the vertices
The other vertices are (0,0) and (0,35/3)
-----
Ans: Choose the vertex that gives you the maximum
number of tables and chairs.
======
Hope this helps.
