Answer:
The total they paid was $58.8685
Step-by-step explanation:
Let us solve the question using the percentage method
∵ Sergio went to dinner with his brother
∵ The bill was $51.19
∵ They left a 15% tip
→ That means they pay extra money 15% of $51.19
∴ The total they paid = the bill + 15% of the bill
∵ 15% of the bill = 15% × 51.19
→ Change 15% to a decimal by divide it by 100
∴ 15% of the bill = × 51.19
∴ 15% of the bill = 0.15 × 51.19
∴ 15% of the bill = $7.6785
→ Substitute it in the total they paid
∵ The total they paid = 51.19 + 7.6785
∴ The total they paid = $58.8685
∴ The total they paid was $58.8685
