Answer: The Smith family price for the meal is $36.39
Step-by-step explanation:
The Smith family went out to dinner. • The price of the meal was $29.85.
The sales tax was 6% of the price of the meal.
LEts find sales tax amount
sales tax amount = price of meal * sales tax 6%(0.06)
= 29.85 * 0.06 = 1.791
sales tax amount = 1.791
Price of the mean with sales tax = 29.85 + 1.791= 31.641
The tip was 15% of the meal and the sales tax
now we find out tip amount for 31.641
15 % is 15/ 100 = 0.15
Tip amount = 31.641 * 0.15 = 4.74615
Now we add the top amount with 31.641
31.641+ 4.74615=36.38715
the Smith family price for the meal = $36.39
