A shopkeeper sells a shirt for $300 after giving a discount of 20%. What was the original price of the shirt? (2020)

Step 1: Let the original price of the shirt be represented by 'x'.
Step 2: The shopkeeper gives a discount of 20%. This means the customer pays 80% of the original price.
Step 3: Write the equation for the price after discount: 0.80 * x = 300.
Step 4: To find 'x', we need to isolate it. We can do this by dividing both sides of the equation by 0.80.
Step 5: Calculate x: x = 300 / 0.80.
Step 6: Perform the division: 300 divided by 0.80 equals 400.
Step 7: Therefore, the original price of the shirt is $400.
