Answer: Gerry has 25 more basketball cards than baseball cards.
Step-by-step explanation:
The total number of sports trading cards that Gerry has is 50.
Of those cards one fifth of them are baseball cards. It means that the number of baseball cards that he has is
1/5 × 50 = 10
one tenth of them are football cards. It means that the number of football cards that he has is
1/10 × 50 = 5
The rest are basketball cards. It means that the number of basketball cards that he has is
50 - (10 + 5) = 35 basketball cards
The difference between the number of basketball and baseball cards that he has is
35 - 10 = 25
