Question 571192
How many tables that can seat 8 and 11 will Mrs.Gordon need to seat 415 people in total? 
----
8x + 11y = 415
---
Solve for "y":
y = (-8/11)x + (415/11)
---
Put that in your graphing calculator and
check tha "Table" for whold number solutions.
----
Ans: x = 23 (# of 8 person tables) 
and y = 21 (# of 11 person tables)
