Final answer:
Little Timmy needs to buy 15 more packs of baseball cards to reach his goal of 150 cards, as he already has 30 and each pack contains 8 cards.
Step-by-step explanation:
Little Timmy needs to reach a total of 150 cards for his baseball card collection. He already has 30 cards, so he needs an additional 120 cards (150 - 30 = 120). Each pack contains 8 cards, so to find out how many packs he needs, divide the number of cards he needs by the number of cards in a pack.
Little Timmy needs to buy 15 more packs of baseball cards to reach his goal of 150 cards, as he already has 30 and each pack contains 8 cards.
120 cards needed ÷ 8 cards per pack = 15 packs
Therefore, Little Timmy needs to buy 15 more packs of baseball cards to reach his goal of 150 cards.
