Answer 1

I just noticed the last line: If you must order at least one of each type of table,

because without that line I was not getting any of your choices.

Can you try to sketch the relations?
Let x be the number of type A and
y be the number of type B

You can order no more than 190 tables this month.
that means the sum of x and y must be less than or equal to 190
x+y≤ 190

put this into slope-intercept form: y ≤ -x + 190
plot the line y= -x + 190
shade the area under this line (this is where y is less than the line)
can you do that?

Answer 2

I'll try :) one sec

It only shows a bit of the graph.
