Final answer:
Jones wins the election because he has more electoral votes.
Step-by-step explanation:
In this election, Jones wins the election. To determine the winner, we look at the electoral votes. State A has 10 electoral votes, and State B has 9 electoral votes. Jones wins in both states, so he gets all the electoral votes. Jones' total electoral votes is 10 + 9 = 19 electoral votes. Smith, on the other hand, wins in State A but loses in State B, so he only gets the electoral votes from State A, which is 10 electoral votes.
In total, Jones gets 19 electoral votes and Smith gets 10 electoral votes. Since Jones has more electoral votes, he wins the election.
