Answer 1

Answer: See explanation

Step-by-step explanation:

Based on the scenario in the question, the amount that the restaurant charge for the lunch excluding any tax will be calculated as:

= $15.40 × 100/(100 + 8)

= $15.40 × 100/108

= $1540/108

= $14.26

Sales tax will be:

= $15.40 × 8%

= $15.40 × 8/100

= $15.40 × 0.08

= $1.23
