Explanation:

Step1: Find the amount of decrease

Subtract the new value from the original value: \( 500000 - 50000 = 450000 \)

Step2: Calculate the percent of decrease

Use the formula for percent decrease: \( \text{Percent Decrease} = \frac{\text{Amount of Decrease}}{\text{Original Amount}} \times 100\% \)
Substitute the values: \( \frac{450000}{500000} \times 100\% = 0.9 \times 100\% = 90\% \)

Answer:

90%
