5. Suppose a consumer would have 5 dental visits a year at the price of $20. When the price rises to $100 per visit, she visits the dentist 3 times a year. Below is the demand curve for this consumer. Demand 250 200 150 Price 100 3, 100 50 5. 20 Quantity A. Calculate the slope of the demand curve. B. What is the demand elasticity from $100 per visit to $20 per visit? Show your calculation. C. Use the slope to calculate how many times will the consumer visit the dentist if he is completely insured? D. When the price of a hospital outpatient dental care visit increases by 10%, visits to dentists increase from 1 to 3 visits. Calculate the cross-price elasticity. Are these two products complementary or substitute goods
