If a 10% decrease in the price of one product that you buy causes an 8% increase in quantity demanded of that product, will another 10% decrease in the price cause another 8% increase (no more and no less) in quantity demanded?

No

Explanation:

to determine if another 10% decrease in the price cause another 8% increase (no more and no less) in quantity demanded, we have to determine the price elasticity of demand.

Price elasticity of demand measures the responsiveness of quantity demanded to changes in price of the good.

Price elasticity of demand = percentage change in quantity demanded / percentage change in price

8% / 10% = 0.8

demand in inelastic so a 10% reduction in price would lead to a less than 8% change in quantity demanded  

Demand is inelastic if a small change in price has little or no effect on quantity demanded. The absolute value of elasticity would be less than one
