Seven lines of arithmetic
Change any assumption you disagree with; the answer follows.
| Estimate actual drinkers | 125 guests × 70% drinking rate | 88 drinkers |
| Calculate base consumption | 88 drinkers × 1.5 drinks/hour × 4 hours | 528 base drinks |
| Apply consumption decay | Adjusted for drinking slowdown over time (decay factor: 3.25) | 429 adjusted drinks |
| Apply holiday party modifier | × 1.15 (+15% for spirits) | 491 spirits servings if served alone |
| Share of the bar | 491 servings × 34.8% | 171 spirits servings |
| Convert to bottles | 171 servings ÷ 17 servings per bottle | 10.1 bottles (raw) |
| Add 15% buffer & round up | 10.1 × 1.15 = 11.6, rounded up | 12 bottles |
