Answer:- A.
c=f(d)=12d,\text{ where d is the number of days}

The input is d.

Step-to-step explanation:-

If 'c' represents the amount of compost produced in 'd' day from yard waste.

Since, the amount of compost produced in one day =12 pounds

Then the compost produce in d days is given by :


c=12* d\\\Rightarrow\ c=12d

Hence, the function represents the relationship between the amount of compost and the number of days is given by :-


c=f(d)=12d,\text{ where d is the number of days}

Since, 'c' is dependent variable which depends on the number of days 'd'.

Therefore, the input is d.
