Answer:
B.It takes more than 12 loads to wash 9 bins of towels.
Step-by-step explanation:
The function f(x) gives the number of loads required when there are x bins of towels to be washed.
f(x)=Number of loads
x=Bins of towels
Therefore in the inequality f(9)>12
- Number of loads=12
- Bins of towel =9
If f(9)>12, it means Number of loads is more than 12.
f(9)>12 therefore tells us that it takes more than 12 loads to wash 9 bins of towels.
The correct option is B
