One out of nine high school students have their own car and drives them to school on daily basis. on a certain day, 1,080 students shows up for school. what is the rough estimate one can assume the number of cars is parked in the student's parking lot using the above-mentioned ratio?

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.
