These figures are called payment profiles and refer to how your contract is structured. The first number before the plus symbol is the number of payments upfront you have chosen. The number after the plus symbol is the remaining number of monthly payments you will have to pay for the car.
In our example (9+47), this is a contract for 48 months or 4 years. The 9 refers to an initial monthly payment of 9 months. After this upfront payment has been made, you will then pay your monthly lease amount for another 47 months.
