On the other hand, Stephanie brought 1/2*30 = 15 eggs to the party.
The total number of eggs that Kelsey and Stephanie brought to Willa's party is 15+12 =27
Alayah brought 27+40 = 67 eggs, 40 more than the number brought by Kelsey and Stephanie combined.
Together with Aliyah's eggs, there were a total of 67+27 = 94
Willa also had 2*30 = 60 eggs from the two trays she had.
In total, there were 94+60 = 154 eggs used at the party.

The answer will be 154.```
