A hydroponic system developer calculates that reducing water evaporation losses by 15% saves 45 liters of water per week. What was the original weekly water usage?
Let \( x \) be the original weekly water usage.
Since saving 15% of \( x \) results in 45 liters, set up the equation:
\( 0.15x = 45 \)
\( x = \frac{45}{0.15} = 300 \text{ liters} \)
