Final Answer : C, Explanation :  The price elasticity of demand formula is percentage change in quantity demanded divided by percentage change in price. A price elasticity of 2.5 means that for every 1% decrease in price, the quantity demanded increases by 2.5%. Here, the price decreases from $2.00 to $1.80, which is a 10% decrease ($0.20/$2.00). Therefore, the quantity demanded would increase by 2.5 times 10%, which equals 25%.
