Kelsey had 2/5 of a tray of eggs that she had brought to Willa's party. Stephanie had also brought half a tray of eggs to the party, while Alayah brought 40 more eggs than Kelsey and Stephanie combined. If Willa had two trays of eggs already, calculate the total number of eggs that were used at the party.
A tray of eggs has 30 eggs, so Kelsey brought 2/5*30 = <<30*2/5=12>>12 eggs
On the other hand, Stephanie brought 1/2*30 = <<1/2*30=15>>15 eggs to the party.
The total number of eggs that Kelsey and Stephanie brought to Willa's party is 15+12 =<<15+12=27>>27
Alayah brought 27+40 = <<27+40=67>>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 = <<67+27=94>>94
Willa also had 2*30 = <<2*30=60>>60 eggs from the two trays she had.
In total, there were 94+60 = <<94+60=154>>154 eggs used at the party.
