1. Aubie Tech wants to expand their current manufacturing process with a new fully automated plastic molding machine. The machine costs $100,000 including shipping and installation fees. It falls into the MACRS 3-year class and it will have an estimated salvage value of $60,000 when sold after 2 years. The machine will be fully financed from a local bank. The payments are made at the end of each year, $59,169.81 annually for the next two years. The loan amortization schedule is given below. With the purchase of the machine, the company will generate $250,000 extra income per year, but considering the electricity usage, machine programming and regular maintenance, it will add expenses of $50,000 annually. Find the present worth of the project if MARR of the company is 15%. Is this expansion economically attractive? (Hint: You need to find after tax cash flows to figure the present worth of this project.)

C++ is the Language. A supermarket has 9 cashiers. Customers arrive and leave at random time intervals. Use 0-5 seconds for this project. The goal of the program is to put the next arriving customer in the shortest queue out of the 9 cashiers. Your program will need to loop infinitely to simulate the passing of a certain amount of time. I suggest looping the program every 50 ms and clearing the screen and displaying all queues. Use a simple for loop as a delay. 1. Needs to be Modular 2. Needs to commented throughout explaining each part 3. Needs to use any mix of arrays, hashes, collision handling etc if applicable
