To find out how many reams of paper Landscape Elementary uses each week, we can divide the total amount of paper used in 3 weeks by the number of weeks:
\[ \text{Reams of paper used each week} = \frac{\text{Total reams used in 3 weeks}}{\text{Number of weeks}} = \frac{14 \text{ reams}}{3 \text{ weeks}} \]
Calculating this gives:
\[ \frac{14}{3} \approx 4.6667 \]
Rounding this to the nearest hundredth:
\[ 4.67 \]
Therefore, Landscape Elementary uses approximately 4.67 reams of paper each week.
