Worked Solution

Step 1: The bag costs $48 after a 20% discount. Step 2: A 20% discount means the buyer pays 100% − 20% = 80% of the original price. Step 3: So 80% of the original price = $48. Step 4: 1% of the original price = $48 ÷ 80 = $0.60. Step 5: 100% (original price) = $0.60 × 100 = $60. Answer: The original price was $60.

Correct answer: $60
