Answer:
$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
