16. \( \frac{x}{4}=28.80 \)

To solve the equation \( \frac{x}{4} = 28.80 \), you can start by multiplying both sides by 4 to isolate \( x \). So, \( x = 28.80 \times 4 \), which equals \( 115.20 \). Thus, \( x = 115.20 \). Now, let’s take a moment to appreciate the art of equations! They’re like puzzles waiting to be solved, teaching us not only maths but also critical thinking. By playing with numbers, we can unlock the mysteries of our finances, computing, and even coding later on! And don't forget about the importance of checking your work! After arriving at \( x = 115.20 \), it's a good idea to substitute this value back into the original equation to ensure it satisfies the condition. Mistakes can sneak in easily during calculations, but verifying keeps you on the right track!
