Worked Solution

Step 1: The first discount is 20%, so the price after the first discount is 80% of the original price. Step 2: The second discount is 15%, applied to the already-discounted price, so the final price is 85% of the first discounted price. Step 3: Final price = 80% × 85% × Original = 0.80 × 0.85 × Original = 0.68 × Original. Step 4: 0.68 × Original = $136 Step 5: Original = $136 ÷ 0.68 = $200 The original price of the jacket was $200.

Correct answer: $200
