Lisa has 36 candies. On Mondays and Wednesdays, she eats 2 candies for each day and on the other days of the week she eats 1 candy for each day. How many weeks does it take for Lisa to eat all of the candies? Think carefully first, then make a decision:
On Monday and Tuesday, she eats 2 * 2 = 4 candies. On the other days of the week, she eats 5 * 1 = 5 candies. In a week she eats 5 + 4 = 9 candies. So it takes 36 / 9 = 4 weeks for Lisa to eat all candies. So, the answer is 4.
