Question

A survey of 75 students was conducted to find out where the seventh grade wanted to go to visit College colleges and universities using this table below if there are three hundred seventh graders how many would you expect would want to go to Clemson University?

Clemson University 30
University of NC 25
NC state University 15
University of south Carolina 5​

Answer 1

For this question, we need to find the unit rate. 7.5 is 10% of 75 (which we can find by dividing 75 by 10). Then, in order to get 30 from this, we would have to multiply 7.5 x 4. Because we multiplied this by 4, that hints to us that 40% of 75 is 30. With this knowledge, we can find 40% of 300, which when doing the math would be 120. Therefore, because 30/75 students would want to go to Clemson University, that means 120 students out of 300 would want to go to Clemson University. Thus, our answer is 120 students
