Reasoning and answer: The normal price of the lessons would be 20 * 40 = $800. The discount saves him 800 * .25 = $200. So the lessons cost him 800 - 200 = $600. That means everything costs 500 + 600 = $1100.
The answer: 1100

If James only missed one question in all five rounds of five questions, he correctly answered 5 * 5 - 1 = 24 questions. Before the bonus, James earned 24 correct answers * 2 points / answer = 48 points. Since missing one question would only disqualify him from receiving a bonus in one round, he would earn a bonus for 5 - 1 = 4 rounds. He should expect a bonus of 4 rounds * 4 points / round = 16 points. Including his bonus, James scored a total of 48 + 16 = 64 points.
The answer: 66
