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

### Instruction:
7 out of 40 people in a cafeteria are wearing checkered shirts. The rest of the people are wearing vertical stripes and horizontal stripes. The number of people wearing horizontal stripes is 4 times as many as the people wearing checkered shirts. How many people are wearing vertical stripes?

### Response:
 Watu 7 wanavaa shati lenye milia, na mara 4 ya watu hao wanavaa milia ya usawa, hivyo 4 * 7 = <<7*4=28>>28 watu wanavaa milia ya usawa.
Jumla ya watu wanaovaa milia ni 28 + 7 = <<28+7=35>>35
Idadi ya watu wanaovaa milia ya wima ni 40 - 35 = <<40-35=5>>5
