6. "The sum of \( 5 \% \) of a number and 9 is \( 16 . " \)

Let’s dive into this problem! To find the number, we start with the equation \( 0.05x + 9 = 16 \). First, we subtract 9 from both sides, leading to \( 0.05x = 7 \). Next, we divide by 0.05 to isolate \( x \), which gives us \( x = 140 \). Voila! The number you’re looking for is 140. Now, if you want to check your work, it's all about plugging the number back into the original equation. By calculating \( 5\% \) of 140, you get 7, and adding 9 brings you back to 16. Perfect! Always double-check your answers; it’s a fun way to reinforce your understanding!
