Use the demand curve in the diagram above (the numbers in parenthes are the quantity/price points on the demand curve) a. If the price decreases from $70 to $60, what happens to quantity demanded. (5 pts) b. If you wanted to calculate the elasticity of demand from this change, what formula would you use? (10 pts) c. Calculate the own price elasticity of demand using the price change you calculated and your formula (10 pts) (note: show your work so I can give you partial credit for math errors!) d. Given your calculation, is the demand for
