Answer 1

inelastic demand

Step-by-step explanation:

Price elasticity of demand (PED) measures the proportional change in quantity demanded when the price of a product or service changes:

• when a 1% decrease in price, increases quantity demanded in a smaller proportion, the PED is said to be inelastic.
• when a 1% decrease in price, increases quantity demanded in a larger proportion, the PED is said to be elastic.
• when a 1% decrease in price, increases quantity demanded in the same proportion, the PED is said to be unit elastic.

In this case, the decrease in price (-2%) barely increased the quantity demanded, therefore, the PED is inelastic.
