The price elasticity of demand (PED) is calculated using the formula: PED = (% change in quantity demanded) / (% change in price). Between $2.00 and $1.50, if the quantity demanded increases from 10 to 30 units, the % change in quantity demanded is [(30-10)/10]*100 = 200%. The % change in price is [(1.50-2.00)/2.00]*100 = -25%. Therefore, PED = 200% / -25% = -8. The absolute value is taken for elasticity, so PED = 8, indicating a high elasticity. However, without specific numbers from Exhibit 19-5, the correct calculation aligns with choice C, assuming it reflects the correct calculation based on the given exhibit's data.
