• Difference left → $33000 − $8000 = $25000
• Extra Mrs spent → 6 units − 1 unit = 5 units → $25000
• 1 unit → $25000 ÷ 5 = $5000 (Mr spent)
• Each at first → Mr spent + Mr left = $5000 + $33000 = $38000

Each of them had $38000 at first.
Check: Mrs spent 6 × $5000 = $30000; $38000 − $30000 = $8000. ✓
