Hey Mate!!
Given ; 300 watches
Watches he sells everyday = w
In One week there are 7 days
So, No of Watches sold in a week = 7 × w = 7w
Now, Watched sold after n weeks = 7w × n = 7wn
Therefore, watches left after n weeks ;
number of total watches - number of watches sold in n weeks.
= 300 - 7wn
Hope this helps you!!
