Let "n" be the number of biscuits.

Then you have this equation to find "n"


     -  = 6   days.


This equation is a literal translation of words to Math.


To solve equation, multiply both sides by 48


    4n - 3n = 6*48

    n       = 288.


ANSWER.  She has  288 biscuits.    (Not bad).

Solved.
