Answer: she baked 1225 muffins.

Step-by-step explanation:

Let x represent the number of muffins that she baked.

She gave 4/11 of the muffins to her friends. This means that the number of muffins that she gave to her friends is 4x/11. The number of muffins remaining is

x - 4x/7 = 3x/7

She gave 4/7 of the remainder to the guests at the event. This means that the number of muffins that she gave to the guests at the event is

4/7 * 3x/7 = 12x/49

The number of muffins remaining would be

3x/7 - 12x/49 = 9x/49

She had 225 muffins left. It means that

9x/49 = 225

9x = 225 * 49 = 11025

x = 11025/9

x = 1225
