Answer: The price was reduced by %.

Type of calculation: Calculating percentage change (decrease).
How to use the calculator: Use the Percentage Change CALCULATOR ("What is the percentage change from the Original value to the New value?"). Enter 200 [Original] and 150 [New]. It will show the percentage decrease.
The formula:
We want the percentage change from 200 to 150.
Formula: ((New value - Original value) / Original value) × 100%
Percentage change = ((150 - 200) / 200) × 100% = (-50 / 200) × 100% = -0.25 × 100% = -25% (the minus sign means a decrease)
