Erwin eats 2 chocolates on weekdays and 1 chocolate on weekends. He ate 24 chocolates in total. How many weeks did it take to finish all the chocolate? Give me reasons, before answering the question
On weekdays he eats 5 * 2 = 10 chocolates. On weekends he eats 2 * 1 = 2 chocolates. He eats 10 + 2 = 12 chocolates in a week. It takes 24 / 12 = 2 weeks to finish all the chocolate. So the final answer is 2.
