Final answer:
Without additional context, it's unclear what the demand between points a and b on a graph is. For a similar situation with cars, an increase in price led to an increase in quantity supplied. This might suggest a status symbol effect or future price expectations for scooters.
Step-by-step explanation:
Suppose the price of scooters is currently $30 per scooter, shown as point a on the initial graph. To answer what the demand between points a and b is, we need additional information regarding the specific shift or movement between those points on the demand curve. However, if we consider a similar context of supply for cars as provided in the reference, where an increase in price from $20,000 to $22,000 per car (ceteris paribus) causes the quantity supplied to rise from 18 million to 20 million cars, we can infer a relationship for scooters as well. If the demand between points a and b shows a similar upward movement, it suggests an increase in the quantity demanded as the price rises, which is atypical and would suggest that the scooters might have a status symbol appeal or that there is an expectation of future price increases.
