Bus Driver's Math 1.2.3

Check if you are an eligible bus driver by calculating the Bus Driver's Math! Your task in this game is to calculate whether the passengers have paid enough money for the bus fare. Each time when the passengers would like to leave the bus, they will pay an amount of money. You need to refer to the list behind the driver's seat to check if the bus fare is enough, then click the corresponding button in the dialogue box before the passengers leave the bus. You will start the game with 3 lives, and if you cannot give an answer before the passengers are gone or if your answer is incorrect, one life will be deducted. When all of the lives are gone, the game ends. Be sure to calculate quickly and do not be tricked by nasty passengers!
