Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
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.

### Response:
 Trei moja ya mayai ina mayai 30, hivyo Kelsey alileta mayai 2/5*30 = <<2/5*30=12>>12
Kwa upande mwingine, Stephanie alileta mayai 1/2*30 = <<1/2*30=15>>15 kwenye sherehe.
Jumla ya mayai ambayo Kelsey na Stephanie walileta kwenye sherehe ya Willa ni 12+15 = <<12+15=27>>27
Alayah alileta mayai 27+40 = <<27+40=67>>67, mayai 40 zaidi ya idadi ya mayai ya Kelsey na Stephanie pamoja.
Pamoja na mayai ya Alayah, jumla ya mayai yalikuwa 67+27 = <<67+27=94>>94
Kwa kuwa Willa pia alikuwa na trei mbili za mayai, jumla ya mayai yaliyotumika kwenye sherehe ni 94+60 = <<94+60=154>>154
