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 × 5 hours | 660 base drinks |
| Apply consumption decay | Adjusted for drinking slowdown over time (decay factor: 3.75) | 495 adjusted drinks |
| Apply 4th of July party modifier | × 1 (0% for spirits) | 492 spirits servings if served alone |
| Share of the bar | 492 servings × 30.4% | 150 spirits servings |
| Convert to bottles | 150 servings ÷ 17 servings per bottle | 8.8 bottles (raw) |
| Add 15% buffer & round up | 8.8 × 1.15 = 10.1, rounded up | 11 bottles |
