3. 40% of the students in a class of 35 students has glasses or contacts. How many students in the dass have either glasses or contacts?

a. What is asked?

  • The number of students that have either glasses or contacts.

b. What are given?

  • 35 students - the number of students in the class and 40% - the rate of students who has glasses or contacts

c. What strategy will solve the problem?

  • Using the formula for finding the percentage: Rate × Base
  • Where 40% is the rate and 35 is the base.

d. What operation will you use?

  • Multiplication

e. Solution

  • Percentage = Rate × Base
  • P = 40% × 35
  • We'll convert the rate into decimal form.
  • P = 0.4 × 35
  • P = 14
