14. In January, the price of dark chocolate candy bars was $2.00, and Willy's Chocolate Factory produced 80 pounds. In February, the price of dark chocolate candy bars was $2.50, and Willy's produced 110 pounds. In March, the price of dark chocolate candy bars was $3.00, and Willy's produced 140 pounds. Using the midpoint method, the price elasticity of supply of Willy's dark chocolate candy bars was about (A)0.70 when the price increased from $2.00 to $2.50 and 0.76 when the price increased from $2.50 to $3.00.
