The Jones family dinner bill is $64.83. They would like to leave a 20% gratuity for their server. How much will their total be if they include the 20% gratuity around the gratuity to the nearest 100

Answer 1

To calculate the total dinner bill including a 20% gratuity, you would follow these steps:

1. Calculate the gratuity: \[ \text{Gratuity} = \text{Dinner Bill} \times \text{Gratuity Rate} \] \[ \text{Gratuity} = 64.83 \times 0.20 = 12.966 \]

2. Round the gratuity to the nearest cent: \[ \text{Gratuity} \approx 12.97 \]

3. Calculate the total bill including the gratuity: \[ \text{Total} = \text{Dinner Bill} + \text{Gratuity} \] \[ \text{Total} = 64.83 + 12.97 = 77.80 \]

4. Round to the nearest hundred: Since $77.80 is closer to $100 than it is to $0, rounding to the nearest hundred would give $100.

Thus, the total for the Jones family dinner, including a 20% gratuity rounded to the nearest hundred, is $100.
