Q. The student population at University X consists of undergraduate students and graduate students. If of undergraduate students and of graduate students wear contacts, what percent of all students wear contacts?Choose answer:(A) (B) (C) (D)
- Calculate Undergraduate Contacts Percent: Calculate the percent of undergraduate students who wear contacts.We know that of the students are undergraduates and of these undergraduates wear contacts. To find the percent of all students who are undergraduates wearing contacts, we multiply these two percentages.
- Multiply Undergraduate Percentages: Perform the multiplication to find the percent of undergraduate students who wear contacts.To express this as a percentage, we multiply by .
- Calculate Graduate Contacts Percent: Calculate the percent of graduate students who wear contacts.We know that of the students are graduates and of these graduates wear contacts. To find the percent of all students who are graduates wearing contacts, we multiply these two percentages.
- Multiply Graduate Percentages: Perform the multiplication to find the percent of graduate students who wear contacts.To express this as a percentage, we multiply by .
- Add Contacts Percentages: Add the percentages of undergraduate and graduate students who wear contacts to find the total percent of all students who wear contacts. (undergraduates who wear contacts) + (graduates who wear contacts) =
- Round Total Percent: Round the total percent to a whole number if necessary.Since the options are given in whole numbers or with one decimal place, we round to the nearest tenth.
