I need help formulating a graphicallinear programming model for this problem.

Obj Fun	Max Z = 5(x1)+13(x2)	$ 130.00
x1	x2
Variables	Tires	Steering Wheels
Values	0	10
Profit	$ 5.00	$ 13.00
Subject to Constraints:	x1	x2	Usage	Sign	Limit
Assy 1	5	4	40	< =	120
Assy 2	7	7	70	< =	70
Logical Model Max Z = 5(x1)+13(x2) 5(x1)+4(x2)<=120 7(x1)+7(x2)<=70 x1, x2>=0
JD Automotive Supply produces 2 different products including Tires and Steering Wheels. For every tire sold JD Automotive Supply makes a profit of $5 and for every steering wheel sold they make a profit of $13. The products are produced on 2 different assembly lines. Assembly line 1 has 120 hours available and assemby line 2 has 70 hours available. On assembly line 1, the tires need five hours while the steering wheels only need 4. Both the steering wheels and the tires require 7 hours on the second assembly line.
