Question

You buy $16 worth of food at a restaurant. The sales tax is 5.75% and you wish to tip 10%. What is the bill after tax, how much tip should you leave, and what is the total cost of everything after you tip?

Answer 1

Sales tax on food = total cost of food x sales tax = $16 x 5.75% = $0.92
Bill after tax = total cost of food + sales tax on food = $16 + $0.92 = $16.92
Tip owned = total cost of food x tip in percent = $16 x 0.1 = $1.60

Total bill = bill after tax + tip owed = $16.92 + $1.60 = $18.52
