Five lines of arithmetic
Change any assumption you disagree with; the answer follows.
| Estimate actual eaters | 20 guests × 95% eating rate | 19 eaters |
| Calculate servings (as main dish) | 19 eaters × 3 pizzas per person | 57 base servings |
| Apply Labor Day party modifier | × 0.8 (-20% for pizza) | 46 pizzas needed |
| Convert to pizzas | 46 pizzas ÷ 8 per pizza | 5.8 pizzas (raw) |
| Add 15% buffer & round up | 5.8 × 1.15 = 6.7, rounded up | 7 pizzas |
Every constant behind this figure is published, including the eating rate by guest count and the 15 percent buffer; read the methodology.
