CHAPTER 3 3. The Olde Yogurt Factory has reduced the price of its popular Mmmm Sundae from $2.25 to $1.75. As a result‚ the firm’s daily sales of these sundaes have increased from 1‚500/day to 1‚800/day. Compute the arc price elasticity of demand over this price and consumption quantity range. Ey = ((1800 – 1500) / ((1800 + 1500) / 2)) ((1.75 – 2.25) / ((1.75 + 2.25) / 2)) Ey = 300 ($4.00) -$0.50 (300) Ey = -8% 4. The subway fare in your town has just been increased from
