Answer:
1250
Explanation:
If Ben has 50 baseball cards in 25 boxes, that means that the total number of cards will be the number of baseball cards per box times the number of boxes. This gives us 50 cards x 25 boxes which can be broken down into 25 x 5 x 10 to make it easier. 25 x 5 = 125 x 10 = 1250 cards.
