Question

Owen and Jesse go to a restaurant for breakfast. A 7% sales tax is applied to their $21.60 bill. If Owen and Jesse add a 15% tip after the tax is applied, what is the total cost, including tip?

Answer 1

The total cost is 26.6 dollars

Explanation:

Given

The total bill of the breakfast = $ 21.60

Sales tax = 7% of the total bill value

Total bill after adding the 7% sales tax

$ 21.60 + 7% of $ 21.60

`21.60 + (7)/(100) * 21.60\\21.60 + 1.512\\23.112`dollars

After adding 15% of the tip values to the payable amount of $ 23.112, the total bill becomes

$ 23.112 + 15% of $ 23.112

`23.112 + 3.4668 = 26.5788`

The total cost is 26.6 dollars
