Question

Enola gave out a survey to some students in her school about their favorite color. Students could choose between blue and purple. 371 of those surveyed said their favorite color was blue. 47% of the students surveyed said their favorite color was purple. How many students were surveyed in total?

Answer 1

Using proportions, it is found that 700 students were surveyed in total.

What is a proportion?

A proportion is a fraction of a total amount.

In this problem, we have that 100 - 47 = 53% of the total number of students had blue as their favorite color, and this amount is of 371, hence:

0.53n = 371

n = 371/0.53

n = 700.

700 students were surveyed in total.
