A wood stove burns 4 bundles of wood in the morning, then some more in the afternoon. If there were 10 bundles of wood at the start of the day and 3 bundles of wood at the end of the day, how many bundles of wood were burned in the afternoon? Give me reasons, before answering the question
Working out the difference between the amount of wood available at the start and the end of the day shows that 10 bundles – 3 bundles = 7 bundles of wood have been burned throughout the day. Subtracting the wood burned in the morning from this shows that 7 bundles – 4 bundles = 3 bundles of wood were burned in the afternoon. So the final answer is 3.
