To find the unit rate of stickers per page, you divide the total number of stickers by the total number of pages.
Given:
- Total stickers = 15
- Total pages = 3
Now, calculate the unit rate:
\[ \text{Unit rate} = \frac{\text{Total stickers}}{\text{Total pages}} = \frac{15}{3} = 5 \]
So, the unit rate is 5 stickers per page.
