gary weight 187 after graduating high school 5 years later he weighs 228 pounds by what percentage has his weight changed

To determine the percentage change in Gary's weight, we'll use the formula:

Percentage change = ((final value - initial value) / initial value) * 100

Given:
Initial weight (after high school) = 187 pounds
Final weight (5 years later) = 228 pounds

Plugging in the values:

Percentage change = ((228 - 187) / 187) * 100

Simplifying:

Percentage change = (41 / 187) * 100

Percentage change ≈ 21.93%

Therefore, Gary's weight has increased by approximately 21.93%.
