Final answer:
The market demand for physician visits, given that individual A purchases 10, B purchases 12, C purchases 14, and D purchases 0, is the sum of all these purchases, which equals 36 visits.
Step-by-step explanation:
The market demand for physician visits is the total number of visits purchased by all individuals in the market. In this scenario, individual A purchases 10 visits, individual B purchases 12 visits, individual C purchases 14 visits, and individual D purchases 0 visits. To calculate the market demand, we simply add the number of visits each individual purchases.Market Demand = Individual A's Visits + Individual B's Visits + Individual C's Visits + Individual D's Visits
Market Demand = 10 Visits + 12 Visits + 14 Visits + 0 Visits Market Demand = 36 VisitsTherefore, the market demand for physician visits in this case is 36 visits.The market demand for physician visits can be calculated by adding up the number of visits purchased by each individual. In this case, individual A purchases 10 visits, individual B purchases 12 visits, individual C purchases 14 visits, and individual D purchases 0 visits. So the market demand is the sum of these numbers: 10 + 12 + 14 + 0 = 36 visits.
