Na survey, 480 people, or 75%, said they attended a movie at least once a month. how many people were surveyed

75% of an unknown number of people is 480 people.
We translate this sentence into an equation and we solve the equation.
Let x = number of people who were surveyed.

75% of x = 480

75% * x = 480

0.75x = 480

x is being multiplied by 0.75. We want x alone, so we divide 0.75x by 0.75 to get x alone. Since we must do the same to both sides of an equation, we divide both sides of the equation by 0.75.





640 people were surveyed.
