Total bill=$95.20
Step-by-step explanation:
Step 1: Determine the subtotal
Subtotal=$85
Step 2: Calculate the amount of the tip
Tip amount=12% of the subtotal
where;
subtotal=$85
replacing;
Tip amount=(12/100)×85=10.20
The tip amount=$10.20
Step 3: Total bill
The total bill can be expressed as;
Total bill=tip amount+subtotal
where;
tip amount=$10.20
subtotal=$85
replacing;
Total bill=(85+10.20)=95.20
Total bill=$95.20
