During a rainy season, the water level in a dam increased by 15% in the first week. In the second week, the level dropped by 20%. If the water in the dam was 45,000 m³ originally, how much water was in the dam after the second week?

In the first week, the level was
(100% + 15%) of 45,000 m³
115% × 45,000 m³ = 51,750 m³
In the second week, the level was
(100% - 20%) of 51,750 m³
80% × 51,750 m³ = 41,400 m³
