Determine whether each statement is true or false. You have one submission for each statement. (a) If demand is unitary when the unit price is p = $4, then revenue will decrease if the unit price is increased slightly from $5. 'True 'False (b) If demand is unitary when the unit price is p = $4, then revenue will decrease if the unit price is increased slightly from $3. 'True 'False (c) Total revenue is decreasing when the demand is elastic and the price is increased slightly. 'True ' False (d) Total revenue is maximized at the equilibrium point. 'True 'False (e) Total revenue is increasing when the demand is inelastic and the price is increased slightly. 'True 'False (f) Total revenue is maximized when the demand is unitary. 'True 'False
