How many winning numbers are there? ** Across all of the lottery tickets, Tony has a total of 3 lottery tickets * 5 winning numbers per lottery ticket = <<3*5=15>>15 winning numbers.
How much money has Tony won in total? ** Across all the numbers, he has won a total of 15 winning numbers * $20 per winning number = $<<15*20=300>>300.
