Vita wants to center a towel bar on her door that is 27.5 inches wide. She determines hat the distance from each end of the towel bar to the end of the door is 9 inches. Write and solve an equation to find the length of the bar.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
