In a sample of students, 125 said they exercise on a regular basis. How large was the sample if 27.3% said they exercised on a regular basis?

Respuesta :

First, let's declare a variable

x = # of students

Now, let's create an equation to model the problem.

x * 0.273 = 125

Divide both sides by 0.273

x = 457.8 = 458 students.

Note, I rounded to the nearest whole number.
