 
 <prompt> 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? 

N'ụlọ ụlọ na-akpọ ground mince maka ndị na-eme lasagnas na cottage pies. Ha na-akpọ 100 lasagnas, ndị na-eme 2 pounds nke ground mince nke ọzọ, na cottage pies, ndị na-eme 3 pounds nke ground mince nke ọzọ. Ọ bụrụ na ụlọ ụlọ na-akpọ 500 pounds nke ground mince n'ime, onye na-eme ka ha na-akpọ cottage pies? <response>: ```The cafeteria used 100 lasagnas * 2 pounds of ground mince = 200 pounds of ground mince for the lasagnas.
This means they used 500 pounds of ground mince in total – 200 pounds of ground mince for the lasagnas = 300 pounds of ground mince for the cottage pies.
So they must have made 300 pounds of ground mince for the cottage pies / 3 pounds of ground mince per cottage pie = 100 cottage pies.

The final answer: 100.```
