Point A on D1 corresponds to a price of $6 per pound and a quantity demanded of 25 million pounds of coffee per month. On the new demand curve D2, the quantity demanded at this price rises to step 35 million pounds of coffee per month (point A?).

A reduction in demand occurs when the quantities of a good or service demanded fall at each price.

The reduction shifts the demand curve for coffee to D3 from D1. The quantity demanded at a price of $6 per pound, for example, falls from 25 million pounds per month (point A) to 15 million pounds of coffee per month (point A?).
