Consider the demand equation given by: Qd = 15 - 2P. You may want to sketch this to refer to when answering this question. Consider what happens when price falls from P = $6 to P = $4. When the price decreases from $6 to $4, overall total revenue will (your answer will either be increase or decrease) by $ (enter a whole number only - no decimals, no commas). This overall effect can be decomposed into a price effect which causes total revenue to (your answer will either be increase or decrease) by $ (enter a whole number only no decimals, no commas) and a quantity effect which will cause total revenue to (increase or decrease) by $ (enter a whole number only no decimals, no commas)
