Question: A shopkeeper sells a shirt for $30 after giving a discount of 20%. What was the original price of the shirt?

A shopkeeper sells a shirt for $30 after giving a discount of 20%. What was the original price of the shirt?

Step 1: Understand that the shopkeeper sells the shirt for $30 after giving a discount.
Step 2: Know that a 20% discount means the customer pays 80% of the original price.
Step 3: Let the original price of the shirt be represented by 'x'.
