Answer:
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
