Question

Of the students in the library, 32% are boys. There are 80 boys in the library. How many students are in the library?

Answer 1

250 students in the library

Explanation:

Let x be the number of students in the library.

We are told that 32% of the students are boys, and that there are 80 of the creatures. We can write that as an equation:

(32%)x = 80 [32% of the total, x, are boys, of which there are 80]

Conert the 5 to decimal value:

(0.32)x = 80

x = (80)/(0.32)

x = 250 students

CHECK:

Does 32% of 250 students equal 80?

(0.32)*(250) = 80 YES
