Answer:
Inelastic
Explanation:
When the price of hamburgers increased from $1.50 to $2.75, the quantity demanded decreased from 375 units sold to 250 units sold. Using the midpoint method, hamburgers are said to be inelastic
1. Change in price = 2.75-1.5 / (1.5+2.75)/2 = 1.25/2.125 = 0.59
2. Change in quantity demanded = 375-250 / (375+250)/2 = 125/ 312.5 = 0.4
3. Price Elasticity = 0.4/0.59 = 0.68
4. When the value of elasticity is less than 1, it suggests that the demand is insensitive to price and is inelastic
