QUESTION 6 Assume the demand for insulin is inelastic. If the price of insulin rises by 5%, the quantity demanded of insulin will Remain unchanged Fall by less than 5% Fall by precisely 5% Fall by greater than 5% QUESTION 7 If some product has an elastic demand, then we can expect total revenue to rise if price falls. price increase to increase total revenue. a smaller percentage change in the quantity demanded, given some percentage change in the price. the absolute value of the elasticity of demand coefficient to be less than one. there are very few substitutes for this product. QUESTION 8 If a demand curve is horizontal—parallel to the quantity axis—then its elasticity is Positive, and less than one Positive, and greater than one Zero Infinity QUESTION 9 Marginal revenue is the change in revenue that results from a one-unit increase in the variable input variable input price output level output price
