Answer:
Kareem requires 864 more cards to reach his goal.
Explanation:
Given;
Kareem has game cards = 216
His goal is to collect = 15 sets
1 set contains = 72 cards.
We need to find how much more card does Kareem required to achieve his goal.
Now we know that;
1 set contains = 72 cards.
15 set contains = how many cards in 15 sets
By using Unitary method we get;
Cards in 15 set = 72 × 15 = 1080 cards
Hence Kareem goal his to achieve 1080 cards.
Now we know that;
Kareem has game cards = 216
To know how much more card does Kareem required we subtract number of cards he has with number of cards to achieve goal.
hence;
Cards required more = 1080 - 216 = 864 cards.
Hence, Kareem requires 864 cards more to achieve his goal.
