Tony bought 3 lottery tickets and chose identical numbers on each ticket. He finds out that 5 of the numbers on each lottery ticket are winning numbers. If each winning number is worth $20 then how much money, in dollars, has Tony won in total?
Thoughts? Step-by-step reasoning:
Across all of the lottery tickets, Tony has a total of 3 lottery tickets * 5 winning numbers per lottery ticket = 15 winning numbers. Across all the numbers, he has won a total of 15 winning numbers * $20 per winning number = $300.
Thus, the answer is 300.
