A clinic focuses on three services: counseling for teens and young adults, smoking cessation, and counseling for young parents. An analyst has developed a forecast of the number of visits each group will make at different prices. Calculate the total quantity demanded at each price. Then graph the relationship between price and total quantity, putting quantity on the horizontal axis.
