Answer:
case 1 elastic demand
case 2 unit elastic demand
case 3 inelastic demand
Step-by-step explanation:
case 1
increases prices = 39 %
total revenue decreases = 67 %
so it is example of elastic demand
because here price increase and that cause decrease in quantity demand
so here we know revenue will be come down
and
case 2
decreases ticket prices = 19 %
total revenue = not change
so it is example of unit elastic demand
because here price change and quantity demand similar
so here we know revenue does not change
and
case 3
increases its prices = 44 %
total revenue increases = 31 %
so it is example of inelastic demand
because here price change is greater than quantity demand
so it cause the increase in total revenue
