## Prompt

After a 20% discount, a jacket costs $40. What was the original price? Show your work.

## Response

The jacket originally cost $50. This follows from the fact that the $40 sale price equals 80% of the original amount after a 20% discount. Dividing the sale price by 0.8 produces the exact original value.

## Step-by-Step Solution
Let the original price be \(x\).

The discounted price satisfies the equation \(0.8x = 40\).

Solving gives \(x = 40 / 0.8 = 50\).
