Option B
2 notebooks for $ 0.60 expressed as unit rate is $ 0.30 per notebook
We have to express ratio as unit rate
Given that, 2 notebooks for $ 0.60
Number of notebooks = 2
Cost of 2 notebooks = $ 0.60
So we have to find cost of 1 notebook
[tex]\begin{array}{l}{\text { cost of } 1 \text { notebook }=\frac{\text { cost of } 2 \text { notebook }}{2}} \\\\ {\text { cost of } 1 \text { notebook }=\frac{0.60}{2}=0.30}\end{array}[/tex]
So unit rate = cost of 1 notebook = $ 0.30
So 2 notebooks for $ 0.60 as unit rate is $ 0.30 per notebook
