Questions & Step-by-Step Solutions
If a shirt is sold for $40 after a 20% discount, what was the original price?
Steps
Concepts
Step 1: Let the original price of the shirt be represented by 'x'.
Step 2: A 20% discount means the shirt is sold for 80% of its original price.
Step 3: Write the equation for the sale price: 0.8 * x = 40.
Step 4: To find 'x', divide both sides of the equation by 0.8: x = 40 / 0.8.
Step 5: Calculate 40 divided by 0.8, which equals 50.
Step 6: Therefore, the original price of the shirt is $50.
