Favorite Type of Book

Find Mystery Percentage: Look at the graph to find the percentage of teens who prefer mystery books.
Calculate Mystery Teens: Calculate the number of teens who prefer mystery books by multiplying the total number of teens by the percentage for mystery. $\newline$ Let's say the graph shows $20\%$ of teens prefer mystery books. $\newline$ Number of teens = $250 \times 20\% = 250 \times 0.20 = 50$ teens.
Find Adventure Percentage: Look at the graph to find the percentage of teens who prefer adventure books.
Calculate Adventure Teens: Calculate the number of teens who prefer adventure books by multiplying the total number of teens by the percentage for adventure. $\newline$ Let's say the graph shows $30\%$ of teens prefer adventure books. $\newline$ Number of teens = $250 \times 30\% = 250 \times 0.30 = 75$ teens.
Find Romance Percentage: Look at the graph to find the percentage of teens who prefer romance books.
Calculate Romance Teens: Calculate the number of teens who prefer romance books by multiplying the total number of teens by the percentage for romance. $\newline$ Let's say the graph shows $25\%$ of teens prefer romance books. $\newline$ Number of teens = $250 \times 25\% = 250 \times 0.25 = 62.5$ teens. But since we can't have half a person, we round to the nearest whole number, which is $63$ teens.
