解題
First, calculate the percentage change in quantity demanded: \(\frac{58,000 - 50,000}{50,000} \times 100 = 16\%\). Second, calculate the percentage change in price: \(\frac{3.60 - 4.00}{4.00} \times 100 = -10\%\). Finally, divide the percentage change in quantity demanded by the percentage change in price to find the PED: \(\text{PED} = \frac{16\%}{-10\%} = -1.6\).
