Answer: The total bill of the lunch = $8.55
Step-by-step explanation:
Cost of lunch= $7.99
Tax rate =7%
Tax amount on lunch = 7% of (cost of lunch)
\(=\frac{7}{100}\times7.99\\=0.5593\approx0.56\)
Therefore, Tax amount on lunch=$0.56
The total bill of the lunch= Cost of lunch+Tax amount on lunch
⇒The total bill of the lunch=$7.99+$0.56
∴The total bill of the lunch= $8.55
