Answer:
Zumba classes sell all 20 participant spots at a price of $4.50 each. When the instructor raised the prices to $5.50, 10 people attended the class. From the midpoint method, the price elasticity of demand for Zumba is:
0.286
Explanation:
20 at $4.50= $90
10 at $5.50= $55
price elasticity= change in quantity demand/ change in price
20-10= 10 change in quantity demand
$90-$55= $35
10/35=0.286
