Question 1107766
120x+360y<16,000
you can use 10 desks, and that is 3600
therefore, 120x+3600< 16000
120x<12400
x<104
(103, 10) would work, and frankly, since the budget is a maximum and not a required maximum, (102, 10) would also work and any number x between 50 and 103 with desks being 10.
If desks were 5
120x<16000-1800=14200
x<119
(118, 5) would work and any x greater than 50 and less than 119 would work.
A graph would include 0 desks (since no lower constraint) and 132 chairs.  
It would also include 103, 10, since that is a maximum, and 118, 5.
Other points would include 50 chairs and 0 desks and 50 chairs and 1-10 desks as well
