Answer:
50
Step-by-step explanation:
Let x represent the number of people that attended the movie.
And y the number of adults that attended the movie
Given;
Percent of adults that attended the movie = 40%
Number of adults that attended the movie y = 20
So,
40% of those that attended the movie area adults.
y = 40% of x
y = 40/100 × x
y = 0.4x
(Ratio of y to x is 4:10 or 0.4)
Making x the subject of formula;
x = y/0.4
Substituting the value of y given;
x = 20/0.4
x = 50
Therefore, 50 people attended the movie.
