Question

Mia and her family went to dinner, and the bill, including tax, came to $54.65. Mia suggested giving the server a gratuity of about 20 percent of the bill. If they give a gratuity of 20 percent, what would be the tip rounded to the nearest dollar? If they give a gratuity of 20 percent, rounded to the nearest dollar, what is the total cost of the dinner, including the tip?

Answer 1

`\huge\boxed{\text{Tip: } \$ 11}`

`\huge\boxed{\text{Total Cost: } \$ 65.65}`

Explanation:

In order to find the percent of something, we need to convert the percent into a decimal.

50% of x can be represented as
`0.5x`, as 50% is half of x and so is 0.5.

This means that 20% of 54.65 will be
`54.65\cdot 0.2`, which is $10.93.

Rounding to the nearest dollar gets us $11.

To find the total cost, we can add $11 (the tip) to the previous cost of $54.65.

`54.65+11=65.65`

Therefore, the total cost of the dinner would be $65.65

Hope this helped!
