The total cost of the meal is $30.02
Step-by-step explanation:
Given,
Cost of meal = $24.62
Tax = 6%
Tax amount = 6% of cost of meal
Cost after sales tax = 24.62+1.48 = $26.10
Tip = 15%
Tip amount = 15% of cost after sales tax
Total cost of meal = Cost after sales tax + Tip amount
Total cost of meal = 26.10+3.92 = $30.02
The total cost of the meal is $30.02
