## Prompt

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

## Response

A 20% discount means the jacket now costs 80% of its original price. So the original price is \(40 \div 0.8 = 50\).

## Work

Let the original price be \(x\).

\[
0.8x = 40
\]

\[
x = \frac{40}{0.8} = 50
\]

## Answer

**$50**
