Answer:
Duane has 192 cards and Tony has 16
Explanation:
If we write an equation and make Tony's amount of cards x, then the equation would be :12x+x=208
Therefore, 13x=208
and x will be 16
That means Tony has 16 cards.
Then since Duane has 12 times of tony's cards and tony has 16, 16*12 is Duane's amount of cards
Therefore Duane has 192 cards
