Gabriel goes to a restaurant and the subtotal on the bill wasxx dollars. A tax of 4% is applied to the bill. Gabriel decides to leave a tip of 16% on the entire bill (including the tax). Write an expression in terms ofxx that represents the total amount that Gabriel paid.

1.16(1.04x)

Step-by-step explanation:

4% tax in decimal is .04. Since the tax is added to the total in x dollars, we need to add .04 to 1 and multiply it by x dollars

We currently have 1.04x

But we still have to account for the additional 16% tip to the entire total after tax. Following the same percent to decimal conversion, we multiply 1.16 to the total of 1.04x to get a final expression:

1.16(1.04x)
