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

### Instruction:
The teacher told the class that if they averaged at least 75% on their final exam, they could have a pizza party. Everyone took the exam on Monday, except for William, who was allowed to take it on Tuesday. If there are 30 people in the class, and the average before he took the test was a 74%, what score does he have to get to make sure they get to have a pizza party?

### Response:
 Hebu x iwe alama ambayo William anahitaji kufikia.
Kwa kuwa kuna watu 30 darasani, kuna watu 30 - 1 = <<30-1=29>>29 bila yeye.
Kwa kuwa wastani wao ulikuwa 74%, hii inamaanisha kwamba (29 * 74 + x) / 30 >= 75.
Hivyo, 29 * 74 + x >= 30 * 75
Hivyo, 29 * 74 + x >= 2250
Hivyo, 29 * 74 + x >= 2250
Hivyo, 29 * 74 + x >= 2250
Hivyo, 2146 + x >= 2250
Hivyo, x >= 2250 - 2146
Hivyo, x >= 94
