###Human: 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?, ### Assistant: 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.
