Answer:
Variable expense
Explanation:
the milk becomes a variable expense because it doesn't have a fixed amount. it could be 2 or 3 or 4 or 1 depending on the number of persons having breakfast everyday over the course of the week but not 5.
if 5 milks are purchased day-in, day-out, the milk would be afixed expense but that isnt the case here.
the term variable expense ffrom the name means an expense that changes or varies from time to time
Cheers.
