Problem Analysis

To solve this problem, we need to determine the total number of foil sheets purchased. We are given that 4 packs of blue foil, each containing 8 sheets, were purchased, as well as the same number of red foil packs, each containing 6 sheets. We need to find the total number of sheets.

Solution 1: Using Multiplication

We can solve this problem by multiplying the number of packs by the number of sheets in each pack for both blue and red foil, and then adding the results together.

Let's calculate the total number of blue foil sheets first: - Number of blue foil packs: 4 - Number of sheets in each blue foil pack: 8

To find the total number of blue foil sheets, we multiply the number of packs by the number of sheets in each pack: 4 packs * 8 sheets/pack = 32 blue foil sheets

Now let's calculate the total number of red foil sheets: - Number of red foil packs: 4 - Number of sheets in each red foil pack: 6

To find the total number of red foil sheets, we multiply the number of packs by the number of sheets in each pack: 4 packs * 6 sheets/pack = 24 red foil sheets

Finally, we add the total number of blue foil sheets and red foil sheets together to find the total number of foil sheets purchased: 32 blue foil sheets + 24 red foil sheets = 56 foil sheets in total

Therefore, a total of 56 foil sheets were purchased.

Solution 2: Using Addition

Alternatively, we can solve this problem by adding the number of sheets in each pack for both blue and red foil, and then multiplying the results by the number of packs.

Let's calculate the total number of blue foil sheets first: - Number of blue foil packs: 4 - Number of sheets in each blue foil pack: 8

To find the total number of blue foil sheets, we add the number of sheets in each pack and multiply by the number of packs: (8 sheets/pack + 8 sheets/pack) * 4 packs = 16 sheets/pack * 4 packs = 64 blue foil sheets

Now let's calculate the total number of red foil sheets: - Number of red foil packs: 4 - Number of sheets in each red foil pack: 6

To find the total number of red foil sheets, we add the number of sheets in each pack and multiply by the number of packs: (6 sheets/pack + 6 sheets/pack) * 4 packs = 12 sheets/pack * 4 packs = 48 red foil sheets

Finally, we add the total number of blue foil sheets and red foil sheets together to find the total number of foil sheets purchased: 64 blue foil sheets + 48 red foil sheets = 112 foil sheets in total

Therefore, a total of 112 foil sheets were purchased.

Conclusion

In conclusion, there are two ways to solve this problem. Using multiplication, we find that 56 foil sheets were purchased. Using addition, we find that 112 foil sheets were purchased.
