Worked Solution
Step 1: The $156 is what REMAINS after spending 35%, so it represents the LEFT-OVER percentage of the original savings.\n
Step 2: Left-over percentage = $100\% - 35\% = 65\%$. So 65% of original = $156.\n
Step 3: Find 1% of the original: $156 \div 65 = \$2.40$.\n
Step 4: Find 100% of the original: $\$2.40 \times 100 = \$240$.\nCheck: 35% of $240 = 0.35 × 240 = $84 spent; $240 − $84 = $156 left. ✓
Answer: $240
Correct answer: $240
