You order an appetizer for $8.99, 2 entrees for $9.99 each, and a dessert for $5.49. the sales tax is 4% and you leave a 15% tip based on the bill with sales tax. what is your total cost of your restaurant outing?

Total cost of restaurant outing is $ 41.21 ( approx )

Step-by-step explanation:

Given,

Cost of an appetizer = $8.99,

One entry fees = $ 9.99,

So, the total entry fees of 2 people = 2 × 9.99 = $ 19.98,

Desert cost = $ 5.49,

Thus, the total cost = $ 8.99 + $ 19.98 + $ 5.49 = $ 34.46,

Sales tax = 4 %,

Thus, the total cost after tax = 104 % of $ 34.46 =  $ 35.8384

Also, there is a tip of 15 %,

Hence, the total cost of restaurant outing = 115 % of $ 35.8384

= 41.21416

≈ $ 41.21
