A project your firm is considering for implementation has these estimated costs and revenues: an investment cost of $50,000; maintenance costs that start at $5,000 at the end of year (EOY) 1 and increase by $1,000 for each of the next 4 years, and then remain constant for the following 5 years; savings of $20,000 per year (EOY 1—10); and finally a resale value of $35,000 at the EOY 10. If the project has a 10-year life and the firm's MARR is 10% per year, what is the present worth of the project? Is it a sound investment opportunity? 

If C= 500 + 0.75Y

C= consumption and Y= disposable income,

GDP is given as $6000.

GDP= Y

1) Find consumption and savings?

2) If GDP increases by $1000, by how much will consumption increase .........750................... and by how much will savings be.........250..............

3) If GDP = $6000, Find APC and APS?

APC is the average propensity to consume and APS is average propensity to save (APC + APS =1).

APC = Consumption/Disposable income

The robot software needs to be implemented and available in the Tinkercad. Please follow the instructions for working collaboratively on the project. build the circuit and write the software, for a robot tracking a beacon whilst avoiding obstacles. The software should control the robot to behave as follows: Startup with a three second delay during which the LEDs must flash. The robot will scan the room, by turning on the spot, to locate an emergency beacon, once detected the robot shall track and proceed towards the beacon whilst avoiding obstacles.
