Given:
Total number of students = 400
Number of high school students = 200
Number of college students = 200
NUmber of college students who chose history = 70
Number of college students who chose math =60
Number of college students who chose science = 70
To find the percentage of the students that are college kids that prefer history, apply the formula below:
[tex]\text{ \% of college that prefers history = }\frac{Number\text{ of college who chose history}}{\text{Total number of students}}\times\frac{100}{1}[/tex]Thus, we have:
[tex]\begin{gathered} \text{ \% of college that prefers history }=\text{ }\frac{70}{400}\times\frac{100}{1} \\ \\ \text{ \% of college that prefers history }=0.175\text{ }\times\text{ 100 = 17.5\%} \end{gathered}[/tex]Therefore, the percentage of the students that are college kids that prefer history is 17.5 percent
ANSWER:
17.5%
