Answer:
Step-by-step explanation:
If we write the description of the relationship between number of cookies (c) and time in hours (t) as ...
c = 40t
then c is the dependent variable and t is the independent variable.
_____
That's not the only way the relationship could be written. Which variable is which depends on how you define them and what you want to know. If you want to know the number of hours to bake "c" cookies, then "c" is the independent variable.
__
This sort of problem statement seems to assume that cookies are being produced continuously, not in batches. In order for any functional relation to properly express the scenario, the domain of the independent variable may need to be restricted to integer hours (or multiples of 40 cookies).
