Answer :
Final answer:
The correct form of a linear demand function given the options is Option A: Qx = 60000 - 100Px. It correctly represents the decrease in quantity demanded for an increase in price.
Explanation:
The question is asking to identify the demand function from the given options. A demand function is typically represented as Qx = a - bPx, where 'Qx' represents the quantity demanded, 'a' is the intercept on the Qx-axis, 'b' is the price elasticity coefficient (slope of the demand curve), and 'Px' is the price of the good or service. Looking at the options given, Option A: Qx = 60000 - 100Px appears to be the correct form of a linear demand function. The term '60000' represents the quantity that would be demanded if the price were zero (the Qx-intercept), and the term '-100Px' shows that the quantity demanded decreases by 100 units for every unit increase in the price.
