Step-by-Step Worked Calculation
Scenario: Splitting a $120 Dinner Bill Among 4 Friends
Calculate an 18% tip and find the cost per person.
Step 1: Identify inputs. Bill = $120, Tip% = 18%, People = 4.
Step 2: Calculate total tip: $120 * (18 / 100) = $21.60.
Step 3: Calculate total bill: $120 + $21.60 = $141.60.
Step 4: Divide by 4 people: $141.60 / 4 = $35.40.
Step 5: Each person pays $35.40, containing a $5.40 tip portion.
