Hello! I made a mistake somewhere on my chart, which is giving me the wrong answer. The right answer is around $170,000, but I got $206,000. Please help ASAP, thanks!

ECO, Inc. manufactures four highly technical products for the semiconductor and medical industries. Each of the products must be assembled, inspected, tested, and packaged for shipping. The profit for each product, as well as the time requirements (in hours) for each stage of each product are shown in the table below. Product Profit Test Assembly Inspection 5.6 1.1 Packaging 1.3 S-09 6.0 4.5 S-10 5.5 1.0 1.3 $1,250 $1,095 $255 $156 3.5 0.4 1.5 0.5 MR-2 XR4 2.6 0.3 0.9 0.4 The amount of labor available in the coming month for each stage of work is shown below, along with the minimum required production for each product.
