Bob's candy factory is considering two different manufacturing systems. System A is highly autonomous with fixed costs of $$45,000$ and variable costs of $$0\mathrm{.}05/$candy$.$ System B uses manually operated equipment that requires several production employees and has fixed costs of $$12,000$ and variable costs of $$0\mathrm{.}1/$candy$.$

What is the crossover point between system A and B$?$
