To find out how many rings of paper Landscape Elementary uses each week, we start by determining the number of rings used per week:
- They use 14 rings every 3 weeks.
- To find the weekly usage, we divide the total by the number of weeks:
\[ \text{Weekly usage} = \frac{14 \text{ rings}}{3 \text{ weeks}} \approx 4.67 \text{ rings/week} \]
Next, we round this number to the nearest 100. However, since 4.67 is significantly lower than 100, rounding to the nearest 100 gives us:
\[ \text{Rounded answer} = 0 \text{ (since 4.67 is closer to 0 than to 100)} \]
Therefore, Landscape Elementary uses approximately 0 rings of paper each week when rounded to the nearest 100.
