Verify betslip calculations: Stake $100.00, Odds 1,221.46, Max Bonus 3.00%. Calculate winnings, bonus, and total payout.

$$\text{Winnings} = \text{Stake} \times \text{Odds}$$ $$\text{Winnings} = 100.00 \times 1,221.46$$ $$\text{Winnings} = 122,146.00$$

$$\text{Bonus Amount} = \text{Winnings} \times \text{Max Bonus Percentage}$$ $$\text{Bonus Amount} = 122,146.00 \times 0.03$$ $$\text{Bonus Amount} = 3,664.38$$

The displayed Bonus on the betslip is 3,664.39. Our calculated bonus is 3,664.38. This is a minor difference of 0.01, likely due to rounding.

$$\text{Total Payout} = \text{Winnings} + \text{Bonus Amount}$$ $$\text{Total Payout} = 122,146.00 + 3,664.38$$ $$\text{Total Payout} = 125,810.38$$

The displayed Payout on the betslip is 125,810.79. Our calculated payout is 125,810.38. There is a difference of 0.41.

The calculations based on the displayed Odds, Stake, and Max Bonus percentage result in a slightly different Bonus and Payout than what is shown on the betslip. This discrepancy suggests that the Odds or Bonus percentage might be used with higher precision internally, or there's a slight rounding difference in the displayed values.

The calculated values are:

• Calculated Bonus: $\boxed{3,664.38}$
• Calculated Payout: $\boxed{125,810.38}$
