In solving a word problem about the farm's animals, what is an appropriate change-unknown scenario?

• A. Find out how many animals remain after some leave.
• B. Determine how many more pigs join the chickens.
• C. Count the total number of animals with new additions.
• D. Identify the remaining number of chickens after losses.

Answer: (C)

In a change-unknown scenario, the focus is on determining the new total after changes have occurred, typically involving additions or subtractions of amounts. In this context, counting the total number of animals with new additions accurately reflects this scenario. The key aspect here is that the problem requires knowledge of how many animals were present initially and how many were added, to arrive at a final total.

This approach aligns well with the idea of tracking changes over time—adding more animals increases the overall count, which is essential in many real-life contexts, such as maintaining an accurate inventory of farm animals. The problem is centered on the effect of those additions, making it a clear example of a change-unknown situation.
