- you've finished eating at a restaurant and received this bill:
      
        - cost: $44.50 
- restaurant tax: 6.75% 
- tip: 15% 
 
- declare the value "meal" and assign it a variable "44.50" 
- declare the value "tax" and assign it a variable "0.0675" 
- tip = 0.15 
- reassign
      
        - meal = meal + meal*tax 
- total = meal + meal*tip
