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

### Instruction:
A school cafeteria uses ground mince to cook lasagnas and cottage pies. They make 100 lasagnas, which use 2 pounds of ground mince each, and cottage pies, which use 3 pounds of ground mince each. If the cafeteria has used 500 pounds of ground mince in total, how many cottage pies did they make?

### Response:
 Wamefanya lasagna 100, ambazo kila moja hutumia pauni 2 za nyama ya kusagwa, hivyo wametumia lasagna 100 * pauni 2 = <<100*2=200>>200 pauni za nyama ya kusagwa kwa lasagna.
Hii inamaanisha wametumia jumla ya pauni 500 - pauni 200 za nyama ya kusagwa kwa lasagna = pauni 300 za nyama ya kusagwa kwa cottage pies.
Hivyo, lazima wamefanya pauni 300 za nyama ya kusagwa kwa cottage pies / pauni 3 za nyama ya kusagwa kwa cottage pie = <<300/3=100>>100 cottage pies.
