(A) 7
(B) 70
(C) 60
Answer: Option A is correct.

Explanation:
The total number of baseball cards does saul has=130
The number of cards in each bag=10
The number of bags=Y
The number of baseball cards needed to get 200 baseball cards overall=X
Already he has 130 baseball cards so we need to find out the extra cards to get 200 baseball cards. If we subtract the cards he has now and the overall cards he wants.
X=200-130
X=70.
Therefore, add 70 to the 130 to get the 200 baseball cards.
Thus, 70 cards are needed to get 200 cards overall.
To calculate the number of bags divide X value and cards in each bag.
Y=70/10
Y=7.
Therefore, 7 bags are needed.
