2 feet, because you aren’t going to have a regular classroom door be 9 feet wide, or have it be 1 foot wide because there are some non really disabled kids but they still have wheel chairs and stuff and it won’t be easy for them to get through a door that is 1 foot wide.
Is there more to this problem? By saying f(4), you'd be inputting a 4 for every variable x. There is not enough info here to answer the question.
The answer is 9
You divide 143 % 11 to get 13. 13 is the number they make an hour, so if you divide 117 % 13 you will get 9.
