Problem 5:

Question: On Halloween night, Nora spent 90 minutes trick-or-treating, Brent spent 60 minutes trick-or-treating, Arnold spent 75 minutes trick-or-treating, and Camille spent 25 minutes trick-or-treating. Which pair spent more total time trick-or-treating: Nora and Camille OR Brent and Arnold?

Step-by-step Solution:

We need to calculate the total time for both pairs.

Pair 1: Nora and Camille
- Nora: 90 minutes
- Camille: 25 minutes
$$
90 + 25 = 115 \text{ minutes}
$$

Pair 2: Brent and Arnold
- Brent: 60 minutes
- Arnold: 75 minutes
$$
60 + 75 = 135 \text{ minutes}
$$

Now compare:
- Nora & Camille: 115 minutes
- Brent & Arnold: 135 minutes

Since 135 > 115, Brent and Arnold spent more time.

✔ Answer: Brent and Arnold

✔ Final Answers:

1) 38 minutes
2) 21 houses
3) 70 candies
4) 125 pieces of candy
5) Brent and Arnold
