Answer:
The answer is 1920, right? Here is how-
The numbers must contain at least three digit and can go above that which means the answer has 3 4 5 and 6 digits all together.
For three digits , there will be 6*5*4 = 120
For 4 Digits, There will be 6*5*4*3=360 possible numbers
For 5 digits , there will be 6*5*4*3*2 = 6! = 720
For 6 digits, there will be 6*5*4*3*2*1 = 6! = 720
<Note- the digits are non repeating as the question said it to be “different digits” >
Now add them up = 120+360+2*720 = 1920

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
