In a survey, 480 people or 75% said they attened a movie at least a month. how many people were surveyed?
i don't get how to find the answer
Do you know algebra?
If so, then let the number of people surveyed be x
then .75x = 480
x = 480/.75 = 640
check: take 75% of 640
480/3= 160
160 is 1/4
160 x 4= 640
640 is whole.
Thx
So my estimet was right
To find the answer, you can set up a proportionate equation using the information given.
Let's assume the total number of people surveyed is represented by 'x'.
According to the information, 75% of the people surveyed attended a movie at least once a month. This can be written as 75% of 'x' (or 0.75x).
Therefore, you can set up the following equation:
0.75x = 480
To solve for 'x', divide both sides of the equation by 0.75:
x = 480 / 0.75
Performing the division, you get:
x = 640
So, the total number of people surveyed is 640.
