Mark and his family went out for dinner for his birthday. The cost of the meal before sales tax was $65.50. The family decides to tip 20% for the good service they received. What tip did Mark pay

$78.6

Step-by-step explanation:

Cost of meal before pay tax = $65.50

If the family decide to tip 20% of the amount of mean for good service, amount tipped will be;

20% of $65.50

= 20/100 × 65.50

= 0.2×65.50

= $13.1

Amount tipped = $13.1

Total amount paid my mark = original cost of food + tip

Total amount paid by mark = $65.5+$13.1

Total amount paid by mark = $78.6
