The letter 'm' stands for the number of notebooks a student wants to buy where m is a variable, which can take any value 1, 2, 3, 4, ... .
The total cost of m notebooks is given by the rule:
The total cost in rupees = 5 × number of note books required
If Munnu wants to buy 5 notebooks, then taking m = 5, we say that Munnu should carry Rs. 5 × 5 or Rs. 25 with him to the school
Similarly, if Appu wants to buy 7 notebook, then he should carry Rs (5 × 7) = Rs. 35
and Sara should carry Rs(5 × 4) = Rs. 20
