Pricing of D-Wave's Quantum Annealer if qbsolv is used

I have the following question: If I use D-Wave's Quantum Annealer via Amazon Braket and if I also use the D-Wave method qbsolv, since my problem instance of my optimisation problem is too large for the quantum processing unit of D-Wave's machine, how exactly will this be charged? To be more precise: Will this still be charged as a single task, no matter how many subproblems qbsolv generates, or will every created subproblem be charged as a single task by Amazon Braket? I will call the method qbsolv only once.

Thanks in advance.
