Billy has 100 sports cards. The number of baseball cards is twice the number of football cards. The number of basketball cards is four more than the number of football cards. Find the number of basketball cards.Please help to solve!
Let the amount of basketball cards Billy has, be B
Then amount of football cards he has = B - 4
Amount of baseball cards he has = 2(B - 4), or 2B - 8
Since he has a total of 100 cards, then we can say that:
B + B - 4 + 2B - 8 = 100
4B - 12 = 100
4B = 112
B, or amount of basketball cards he has = , or
