Solve the problem.
Zoe counted 40 kinds of walking stick insects one day on a nature hike. The next day, she spotted 25 kinds of walking sticks; however, 14 of the insects she counted on the second day were the same as the ones she had counted on the first day. How many different kinds of walking sticks would Zoe have seen if none of the insects she saw on the second day were the same as the ones she saw on the first day?
To find the number of different kinds of walking sticks Zoe would have seen if none of the insects she saw on the second day were the same as the ones she saw on the first day, we need to subtract the number of insects that were the same on both days from the total number of insects she saw on the second day.
Total number of insects Zoe saw on the second day = 25
Number of insects that were the same on both days = 14
Number of different kinds of walking sticks Zoe would have seen = Total number of insects Zoe saw on the second day - Number of insects that were the same on both days
= 25 - 14
= 11
Therefore, Zoe would have seen 11 different kinds of walking sticks if none of the insects she saw on the second day were the same as the ones she saw on the first day.
