Problem Description:
The task involves calculating the total cost of purchasing water bottles for a school event. The image provides the following details:
1.
Number of students: 240
2.
Number of water bottles per student: 3
3.
Cost per water bottle: $0.50
The goal is to determine the total number of water bottles needed and the total cost.

Step-by-Step Solution:
####
Step 1: Calculate the total number of water bottles needed
Each student requires 3 water bottles, and there are 240 students. Therefore, the total number of water bottles can be calculated as:
\[
\text{Total number of water bottles} = \text{Number of students} \times \text{Water bottles per student}
\]
\[
\text{Total number of water bottles} = 240 \times 3 = 720
\]
####
Step 2: Calculate the total cost
The cost of each water bottle is $0.50. To find the total cost, multiply the total number of water bottles by the cost per bottle:
\[
\text{Total cost} = \text{Total number of water bottles} \times \text{Cost per water bottle}
\]
\[
\text{Total cost} = 720 \times 0.50 = 360
\]

Final Answer:
\[
\boxed{720 \text{ water bottles, } \$360}
\]

Explanation:
1.
Multiplication for Total Bottles: The total number of water bottles is determined by multiplying the number of students by the number of bottles each student needs.
2.
Multiplication for Total Cost: The total cost is calculated by multiplying the total number of water bottles by the cost per bottle.
3.
Units: Ensure that the units are consistent throughout the calculation (e.g., bottles and dollars).
This method ensures accuracy and clarity in solving the problem.
