Option B
2 notebooks for $ 0.60 expressed as unit rate is $ 0.30 per notebook
<h3><u>Solution:</u></h3>
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

So unit rate = cost of 1 notebook = $ 0.30
So 2 notebooks for $ 0.60 as unit rate is $ 0.30 per notebook
P-x= -10
Now to isolate x divide both sides by p
-x = -10/p
But x can not be a negative do distribute a negative 1 to both sides and your answer is :
x = 10/p
