f(1) &= a + b + c + d =Ali has 120 liters of water stored in a tank. Each day, 15 liters are used for farming and 5 liters evaporate. How many full days will the water last before it runs out?

**How Long Can a 120-Liter Water Tank Last When Daily Loss Adds Up? A Real-World Look** In a growing conversation across U.S. rural communities and water-stressed regions, users are asking a straightforward but critical question: *How long will stored water last when daily consumption and losses combine?* Take Ali’s 120-liter tank, where 15 liters vanish daily through farming and another 5 liters evaporate into dry air. What does math and real-world usage reveal about how long this supply holds? This equation—f(1) = a + b + c + d—represents more than just numbers: it’s a lens into resource planning, scarcity, and sustainability. ### Why This Question Matters Now Water conservation isn’t just an agricultural issue—it’s a national conversation. Droughts, shifting rainfall patterns, and rising demand have pushed communities to scrutinize every drop. With farming consuming a major share of freshwater in the U.S. and even home water use becoming pricier or restricted in some drought-prone states, understanding how reserves deplete helps farmers, homeowners, and planners make smarter decisions. This formula—f(1) = a + b + c + d—encapsulates daily water outflows from multiple sources: actual use, evaporation loss, and the cumulative effect on stored supply.
