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:
[tex]48\cdot0.15=7.20[/tex]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
[tex]48+7.20=55.20[/tex]The total bill will be $55.20
