Worked Solution
Step 1: Identify what the sale price represents.
A 30% discount means Siti paid (100% − 30%) = 70% of the original price.
Step 2: Set up the equation.
70% of original price = $63
Step 3: Find 1% of the original price.
1% = $63 ÷ 70 = $0.90
Step 4: Find 100% (the original price).
100% = $0.90 × 100 = $90
The original price of the shoes was $90.
Correct answer: $90
