Calculating the Number of Different Notepads Made by Vanya

To calculate the number of different notepads Vanya made, we can use the information provided. Vanya had 224 sheets and made 30 notepads, with each notepad containing either 7 or 9 sheets.

Calculation

To find the number of different notepads Vanya made, we can use the following steps:

1. Calculate the total number of sheets used: - 30 notepads * 7 sheets/notepad = 210 sheets from the 7-sheet notepads - 30 notepads * 9 sheets/notepad = 270 sheets from the 9-sheet notepads - Total sheets used = 210 + 270 = 480 sheets

2. Determine the number of different notepads made: - As Vanya had 224 sheets, it's not possible to make 30 notepads with 7 or 9 sheets each using only 224 sheets. Therefore, there seems to be a discrepancy in the provided information.

Conclusion

Based on the provided information, it seems there might be a mistake in the given numbers. The total number of sheets required to make 30 notepads with 7 or 9 sheets each exceeds the 224 sheets Vanya had. If there are any additional details or corrections to the information, please provide them for a more accurate calculation.
