Answer: e. inelastic; increased
Step-by-step explanation:
Aspirin is a pain medication which means that those who take it likely need it or are addicted to it. Either of these would lead to the person having an inelastic demand for it.
This means that if the company producing aspirin were to increase the price, the person would still buy aspirin and this would increase the revenue of the company because they would be making more per drug.
