Seven lines of arithmetic
Change any assumption you disagree with; the answer follows.
| Estimate actual drinkers | 300 guests × 65% drinking rate | 195 drinkers |
| Calculate base consumption | 195 drinkers × 1.5 drinks/hour × 4 hours | 1170 base drinks |
| Apply consumption decay | Adjusted for drinking slowdown over time (decay factor: 3.25) | 951 adjusted drinks |
| Apply March Madness party modifier | × 0.85 (-15% for spirits) | 808 spirits servings if served alone |
| Share of the bar | 808 servings × 26.1% | 211 spirits servings |
| Convert to bottles | 211 servings ÷ 17 servings per bottle | 12.4 bottles (raw) |
| Add 15% buffer & round up | 12.4 × 1.15 = 14.3, rounded up | 15 bottles |
