Last Sunday, 1,575 people visited the amusement park. 56% of the visitors were adults, 16% were teenagers, and the rest were children ages 12 and under. How many children under 12 visited the park?
First we less the sum of 56% and 16% from 100% to get our percentage of visitors under 12. [tex]100 - (56 + 16) = 28[/tex] Percentage of visitors under twelve = 28%
Then we take 28% of 1,575. Easiest done if we use the fraction .28 instead of 28%. [tex]1575 \times 0.28 = 441[/tex] Number of visitors under twelve= 441
