Final answer:
A group of 12 students went to the amusement park. 2 students went to the Funhouse, 6 students got a snack, and 15 students went to the park.
Step-by-step explanation:
Let's go step by step to find the number of students who went to the Funhouse, got a snack, and went to the amusement park.
A. To find the number of students who went to the Funhouse, we need to multiply the remaining students after the snack by 1/3. The remaining students after the snack are 1/2 * 12 = 6.
So, 1/3 of 6 is 6 * 1/3 = 2 students went to the Funhouse.
B. To find the number of students who got a snack, we need to find 1/2 of the total number of students. 1/2 * 12 = 6 students got a snack.
C. To find the number of students who went to the amusement park, we need to add up the number of students at each activity: 6 (snack) + 3 (water slide) + 2 (Funhouse) + 4 (roller coaster) = 15 students went to the park.
