Q. The depth of a lake in Centerville changes over time due to rainfall and evaporation. A few months ago, the depth was 6565 feet. Currently, the depth is 5252 feet. By what percent has the depth of the lake decreased?\newline____%\_\_\_\_\%
  1. Calculate change in depth: Calculate the change in depth of the lake.\newlineOriginal depth = 6565 feet, Current depth = 5252 feet.\newlineChange in depth = Original depth - Current depth = 65−52=1365 - 52 = 13 feet.
  2. Calculate percentage decrease: Calculate the percentage decrease in depth.Percentage decrease=Change in depthOriginal depth×100\text{Percentage decrease} = \frac{\text{Change in depth}}{\text{Original depth}} \times 100.Percentage decrease=1365×100=20%\text{Percentage decrease} = \frac{13}{65} \times 100 = 20\%.
