The bill without tip is $48.00
To calculate the total bill with tip, considering that you want to leave a 15% tip, you have to calculate how much is the 15% of $48.00. To do so, multiply 48 by 0.15:
![48\cdot0.15=7.20](https://img.qammunity.org/2023/formulas/mathematics/college/yybfjbr4wiwai407ok36xfza38mjndhgud.png)
The amount that corresponds to a 15% tip is $7.20
To calculate the total bill, tou have to add the bill plus the tip
![48+7.20=55.20](https://img.qammunity.org/2023/formulas/mathematics/college/bfewhh4znidqpgupwe6c1xpu1kiec5fpz7.png)
