To determine how many reams of paper Landscape Elementary uses each week, we can start by calculating the usage per week based on the total usage over 3 weeks.
They use 14 reams of paper in 3 weeks. To find the weekly usage, we can divide the total by the number of weeks:
\[ \text{Weekly usage} = \frac{14 \text{ reams}}{3 \text{ weeks}} \approx 4.6667 \text{ reams/week} \]
Now, to round this to the nearest hundredth:
\[ 4.6667 \text{ rounded to the nearest hundredth is } 4.67 \]
Thus, Landscape Elementary uses approximately 4.67 reams of paper each week.
