Question

Kaylee surveyed 920 of the students in her school about their favorite color. 95% said

their favorite color was blue. How many students' favorite color was blue?

Answer 1

x = 874

Explanation

Set up your equation like this: Part/whole = percent/100

Assign the variable x to the unknown part of the equation and add in the known numbers:

So in this situation it would be: x/920 = 95/100

Solve for x:

100 times X = 920 times 95. (cross multiply)

That leaves you with 100x = 87,400

Divide both sides by 100:

x = 874
