Question: Every tree that Bart cuts down gives him 75 pieces of firewood. If he burns 5 logs a day from November 1 through February 28, how many trees will he need to cut down? Think carefully first, then make a decision:
November has 30 days, December has 31 days, January has 31 days and February has 28 days for a total of 30 + 31 + 31 + 28 = 120 days. He burns 5 pieces of wood every day so 120 * 5 = 600 pieces of wood. Every tree he cuts down supplies 75 pieces of firewood and he will burn 600 pieces so he needs 600 / 75 = 8 trees. So the answer is 8.
