## Prompt

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

## Response

After a 20% discount, the jacket costs $40, meaning the sale price represents 80% of the original price. Let the original price be \( P \). Then:

\[
0.80 \times P = 40
\]

Divide both sides by 0.80:

\[
P = \frac{40}{0.80} = 50
\]

The original price was **$50**.
