To find the unit rate of flowers per base, you can divide the total number of flowers by the total number of bases (or faces).
Given:
- Total flowers = 112
- Total bases = 14
Now, calculate the unit rate:
\[ \text{Unit rate} = \frac{\text{Total flowers}}{\text{Total bases}} = \frac{112}{14} = 8 \]
So, the unit rate of flowers per base is 8.
The answer is B. 8.
