Question 82799
an x takes 12 hours to build and a y takes 20 hours ... there are 800 hours available ... 12x+20y<=800 or 3x-5y<=200


total capacity is 50 ... x+y<=50


to cover exsisting orders ... x>=10, y>=15


graph the inequalities like equations ... after you draw the line, pick a point on one side and see if it satisfies the inequality - if it does, then shade that side as the solution - if not, shade the other side
