The money they have isn’t accepted.
They have nothing to barter with.
Yet, “Another solution will present itself” is the attitude of Qui-Gon Jinn, he is keeping his eyes open to opportunity.
And in the end Qui-Gon Jinn doesn’t use any money to get what he wants. His solution (crazy as it is) involves winning the prize money for a race happening the next day. A race for which he has no vehicle to race and no money to pay the entrance fee either.
The young Anakin Skywalker offers to help them out by flying in the race using the ‘Podracer’ he has built. The lack of entrance fee doesn’t Stop Qui-Gon Jinn either and with some clever negotiation he ends up working a deal with Anakin’s slave owner whereby (after a hair raising race full of all the thrills and spills you would expect from a sci-fi film), he ends up with all the parts he needs and pays off the young Anakin’s slave debt, thereby freeing him from a life of slavery. All from simply being open to opportunities.
Ok nice film but how does this apply to the real world?
