| Major at ABC University | ||||
| Gender | Humanities | Math/Science | Engineering | Total |
| Male | 450 | 125 | 140 | 715 |
| Female | 520 | 100 | 155 | 775 |
| Total | 970 | 225 | 295 | 1490 |
What is the total percentage of STEM majors (math, science, engineering) out of all the students at ABC University, rounded to the nearest percent? (Ignore the percent symbol when entering your answer. For example, if your answer is 10%, enter 10 as your answer.)
Correct Answer: 35
Explanation:
(35) The number of math/science majors is 225, and the number of engineering majors is 295. So the total number of STEM majors is 225 + 295 = 520. The total number of students at the university is 1,490. Therefore, the total percentage of STEM majors at the university is:
When rounded to the nearest percent, we get 35%.
