 Consumer math Tipping A tip (also called a gratuity) is a payment made to certain service sector workers in addition to the price of the service. Some of the people we tip are taxi drivers, waiters, hair dressers or barbers. Below are some guidelines for how much to tip: • Hair dresser or barber: 15% • Food delivery: 10% • Waiter: 15% – 20% (depending on service) • Bartender: 15% – 20% (depending on service) • Taxi: 15% The amount of a tip is usually calculated as a percentage of the transaction value before taxes. The Trey family went out for dinner. Their total bill before taxes came to $56.89. They want to give a 15% tip. How much should they tip the waiter? Round your answer to the nearest dollar. Step 1: Convert 15% into a decimal: .15 Step 2: Multiply$56.89 x .15 = $8.53 Step 3: Round off to nearest dollar:$9.00 The Trey family should leave $9.00 for their waiter. Helen got her hair cut and coloured. It cost$105 before taxes. She wants to give a 15% tip. How much should she tip the hair dresser? Round your answer to the nearest dollar. Step 1: Convert 15% into a decimal: .15 Step 2: Multiply $105 x .15 =$15.75 Step 3: Round off to nearest dollar: $16.00 The Trey family should leave$16.00 for their waiter.
