Final answer:
The question as asked cannot be answered without additional information regarding the price per 4x7 card. However, if the price were known, the total cost for 48 cards would be the price per card multiplied by 48. The unrelated information about card permutations and magazine purchases cannot be applied to solve the posed question.
Step-by-step explanation:
The provided prompt does not offer enough information to directly answer the question about the cost of 48 or more 4x7 cards, as it does not state the price of the cards. The information given discusses a scenario involving eight shuffled cards of different colors and an unrelated question about buying magazines. Additionally, there is a reference to the concept of combinations as illustrated through the permutation of four items (4!).
To deal with the potential confusion, let's address the principles that might be relevant to questions like these in a general sense. The cost of a number of items can be calculated by multiplying the price of one item by the total number of items. If you were to know the price per card, you could simply multiply that by 48 to obtain the total cost for 48 cards. If the price per card is unknown, this multiplication cannot be specifically carried out.
In the case of permutations and combinations, as exemplified by the mention of 4!, permutations refer to the arrangement of items where the order matters. For example, the number of ways to arrange four cards is indeed 4! (4 factorial), which equates to 4×3×2×1, resulting in 24 different combinations. Understanding this helps in solving problems related to probability and counting principles.
