D. $16.80 for lunch and $1.34 for sales tax.

option (B) $15.56 for lunch and $1.24 for sales tax

Explanation:

Data provided in the question:

Total bill including sales tax = $16.80

Sales tax = 8% = 0.08

Now,

let the price of lunch be 'x'

Therefore,

Price for lunch + sales tax = Total bill including sales tax

⇒ x + (8% of x) = $16.80

or

⇒ x + 0.08x = $16.80

or

⇒ 1.08x = $16.80

or

⇒ x = $15.56

therefore,

The price for the lunch = $15.56

Sales tax = $16.80 - $15.56

= $1.24

Hence,

option (B) $15.56 for lunch and $1.24 for sales tax
