Joe has a collection of 280 sports cards which is 100% of his cards.
Baseball Cards are 30% of Total Cards
Football Cards are 25% of Total Cards
Basketball cards = Total Cards - Baseball Cards - Football Cards = 100% of Total Cards - 30% of Total Cards - 25% of Total Cards
= (100-30-25)% of Total Cards = 45% of Total Cards
= \(\frac{45}{100}\) * 280 = 126 Cards
So, Answer will be C
Hope it helps!
