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?

An estimate of 120 cars will be parked.

Step-by-step explanation:

We can easily solve this problem by applying a rule of three

1 student with car    9 students

x 1080 students

x = 1*(1080/9)  

x = 120 students with car

An estimate of 120 cars will be parked.

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
