Yes I need to graph and solve the equation.
To learn how to graph the solutions to systems of linear inequalities, please study this lesson
1A<= 100 is a vertical line on the graph (I think it is vertical, but I am not sure. My reasoning is A is on the X axis)
another question about my graph; starting from the Orgin if "0" do I start my numbers at 100, 200, 300 ... or since the distance is so close should I do in increments of 10s --- 10,20, 30
I think the above refers to the numbering on the axes. If so, then use whatever units you
find useful and helpful.
1B<= 80 is a horizontal line on the graph
2A + 4B <= 400 here is where I am stuck.
Solve the inequality for whichever variable you've put on the y-axis. (To learn how to solve linear equations for "y", try here
.) Then graph as usual (shown in the first lesson link, above.)
My extreme points are (100,50) and (40,80) where do I go from here, not sure what this means as it relates to 5A + 5B.
Then you plug the extreme points into the optimization equation, and see which one is the best fit to the requirements of the exercise. For worked examples, please review this lesson
