Sagot :

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
