Need some help on solving this problem. Especially the constraint of the model 2

Suzuki Robotics (SR) manufactures two lightweight robots designed for easier house-cleaning. The Alpha-ONE model is older, heavier, and is designed for carpet cleaning. The Alpha-TWO model is newer, lighter, and is designed primarily for wooden floor cleaning. SR produces the components for both models at its Indiana plant. Each Alpha-ONE model requires 3 hours of manufacturing time and each Alpha-TWO model requires 4 hours of manufacturing time. The Indiana plant has 1000 hours of robot manufacturing time available for the next production period. The frames for each model are obtained from a third-party supplier, who can supply as many Alpha-ONE frames as needed. However, Alpha-TWO frame is newer and lighter, and the supplier can only provide up to 300 Alpha-TWO frames for the next production period. Final assembly and testing require 3 hours for each Alpha-ONE model and 2 hours for each Alpha-TWO model. Maximum of 600 hours of assembly and testing time are available for the next production period. The company's accounting department projects a profit contribution of $300 for each Alpha-ONE model produced and $250 for each Alpha-TWO model produced. You can either solve this problem graphically or by using Solver in Excel and then fill the blanks below: a. The optimal value for the manufacturing of the Alpha-ONE Model is b. The optimal value for the manufacturing of the Alpha-TWO Model is c. The Maximized profit value is $ d. The binding constraints are and
