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

### Instruction:
Jenny signs up for dinner theater with 5 of her friends. Each person pays $50 for the ticket and $10 for their entrée, and half the people also buy unlimited drink tickets for $30/person. Then the dinner theater is canceled due to COVID, and each person gets a 90% refund. How much money did the group of six friends lose?

### Response:
 Kwanza, marafiki sita hulipa $50/kila mtu * watu 6 = $300 jumla kwa tiketi.
Kisha, hulipa $10/kila mtu * watu 6 = $60 jumla kwa chakula.
Kisha watu 3 hununua tiketi za vinywaji kwa $30/kila mtu * watu 3 = $90.
Basi bila vinywaji, marafiki walilipa $300 + $60 = $360.
Pamoja na vinywaji, marafiki walilipa $360 + $90 = $450.
Wanapata marejesho ya $450 * 0.9 = $405.
Hivyo marafiki walipoteza $450 - $405 = $45.
