Situation 2: A bad day
In the morning
Numericus begins to work at nine o’clock. It takes him twenty minutes to get from home to the station. He has breakfast in fifteen minutes. It takes him thirty minutes to walk the dog. And he spends ten minutes in the bathroom. At what time does he have to wake up to get on time?
Leaving home
Numericus lives on the fourth floor. This morning when he got in the elevator something went wrong and he first went up three floors to the last one. Then he went down five floors, up three, seven down and finally he went up two floors. How many floors does the building have?
At work
Numericus arrives at work a little late because of the elevator ride. At noon the system breaks. The boss says they can not close the station so he must do all the calculations by hand. Look at the price table and help Numericus to find how much each client must pay.
Client 1: 54 liters of petrol + water
Client 2: 15 liters of diesel + Sandwich + chips
Client 3: 50€ of petrol + coffee
Client 4: 20€ of diesel + bread
The last client
Before his shift ends a new customer arrives.
Client: Good afternoon, I would like to fill the tank with 43 liters of petrol.
Numericus: Anything else?
Client: yes, I would like water, tuna Sándwich and chips but I only have 60€.
Numericus: Ok. All it would be …
How much does this customer must pay? Does he have enough money? There would be some money left?
