Over a two-week span, John ate 20 pounds of chicken wings and 15 pounds of hot dogs. Kyle ate 20% more wings and 40% more hot dogs. Kyle ate approximately x% more food by weight than John. What is x (nearly rounded)?

Correct answer: 30. Kyle ate 24 + 21 = 45 lb against John’s 35 lb. The extra is 10 lb, and 10 ÷ 35 × 100 ≈ 28.57%, which is nearly 30%.

Background: Percentage more = (extra ÷ original) × 100.

• 20: 20% is below the calculated increase.
• 45: 45% is above the calculated increase.
• 50: 50% is above the calculated increase.

Did you know? Always divide by the original amount (John’s).

Memory trick: Extra ÷ John’s total.
