On Monday, Linus made 5k paper cranes and gave 2k paper cranes to his friends. On Tuesday, he made another 4k paper cranes. His friend gave him 5 paper cranes. How many paper cranes does he have now in terms ok k?

Respuesta :

First of all do 5k-2k=3k.
Then he made 4k more, so now he has 7k cranes.
Then his friend gave him 5 more which makes 7k+5 cranes.

((5k-2k)+4k)+5
