Answer:
B. It takes more than 12 loads to wash 9 bins of towels.
Explanation:
The function f(x) gives the number of loads
Where x= bins of towels
If f(9) > 12
- Number of bins of towels =9; and
- Number of Loads, f(x)>12
Therefore, f(9) > 12 tells us that it takes more than 12 loads to wash 9 bins of towels.
The correct option is B.
