Consider the following demand equation:
Q = 206 - 15p - 10po + 0.18Y
Here p is the price of the good, po is the price of a related good, and Y is income.
If we assume the price of the related good is held fixed at $10 and that income is held fixed at $40,000, calculate quantity demanded when its price is $2. Round your answer to the nearest whole number as needed; carefully follow all other numeric instructions.
