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

### Instruction:
A group of 300 athletes spent Saturday night at Ultimate Fitness Camp. The next morning, for 4 hours straight, they left the camp at a rate of 28 athletes per hour. Over the next 7 hours, a new group of athletes trickled into the camp at a rate of 15 athletes per hour. Immediately thereafter, the camp gate was shut and everyone went to bed. What is the difference in the total number of athletes in the camp over the two nights?

### Response:
 Asubuhi ya kwanza, idadi ya waliotoka kambini ilikuwa 4*28 = <<4*28=112>>112 wanamichezo.
Hii inamaanisha kuwa baada ya asubuhi ya kwanza, kulibaki wanamichezo 300-112 = <<300-112=188>>188.
Katika masaa 7 yaliyofuata, kundi jipya lililokuwa likiingia lilikuwa na wanamichezo 15*7 = <<15*7=105>>105.
Idadi ya wanamichezo kambini mwisho wa siku ni 188 + 105 = <<188+105=293>>293 wanamichezo.
Kwa kuwa hakukuwa na harakati yoyote ndani au nje ya kambi usiku wa pili, idadi ya wanamichezo kambini usiku wa pili ni 293 wanamichezo.
Tofauti katika idadi ya jumla ya wanamichezo kambini kwa usiku wa Jumamosi na Jumapili ni 300 - 293 = <<300-293=7>>7 wanamichezo.
