Two drivers --- Tom and Jerry --- each drives up to a gas station. Before looking at the price, each places an order. Tom says, "I'd like 10 gallons of gas." Jerry says, "I'd like $10 of gas."
• What is Tom's price elasticity of demand and what does his demand curve look like (either verbally explain the shape of the demand curve or give an equation for the demand curve)?
• What is Jerry's price elasticity of demand and what does his demand curve look like (either verbally explain the shape of the demand curve or give an equation for the demand curve)?
