To find the usage of paper per week, we can divide the total amount of paper used every 3 weeks by the number of weeks.
Given:
- 14 reams of paper are used in 3 weeks.
We can calculate the weekly usage as follows:
\[ \text{Weekly usage} = \frac{\text{Total reams}}{\text{Number of weeks}} = \frac{14 \text{ reams}}{3 \text{ weeks}} \approx 4.67 \text{ reams/week} \]
So, Landscape Elementary uses approximately 4.67 reams of paper each week. If you need more information or calculations, feel free to ask!
