Q. The results of a survey asking teens their favorite type of book to read is shown.

\newline

7

. Out of

250

teens, predict how many would choose mystery as their favorite type of book to read.

\newline

8

. Out of

250

teens, predict how many would choose adventure as their favorite type of book to read.

\newline

9

. Out of

250

teens, predict how many would choose romance as their favorite type of book to read.

\newline

Favorite Type of Book

Calculate Percentages: First, we need the percentage of teens who prefer each type of book. Let's assume the survey results are as follows: $30\%$ for mystery, $40\%$ for adventure, and $30\%$ for romance.
Calculate Mystery Teens: To predict how many teens would choose mystery, we calculate $30\%$ of $250$ . $\newline$ $30\%$ of $250 = 0.30 \times 250 = 75$ teens.
Calculate Adventure Teens: Next, we calculate $40\%$ of $250$ for adventure. $\newline$ $40\%$ of $250 = 0.40 \times 250 = 100$ teens.
Calculate Romance Teens: Lastly, we calculate $30\%$ of $250$ for romance. $\newline$ $30\%$ of $250$ = $0.30 \times 250$ = $75$ teens.
