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?

5k - 2k + 4k + 0.005k = 7.005k.

Let's break down the problem step by step to find the final number of paper cranes in terms of 'k'.

1. On Monday, Linus made 5k paper cranes.
2. He gave 2k paper cranes to his friends.
3. So, out of the 5k paper cranes, he will have 5k - 2k = 3k paper cranes left.

Now, let's move on to Tuesday's activities:

4. On Tuesday, Linus made another 4k paper cranes.
5. His friend gave him an additional 5 paper cranes.
6. So, the total number of paper cranes after Tuesday's activities is 3k + 4k + 5 = 7k + 5.

Therefore, in terms of 'k', Linus has 7k + 5 paper cranes after all these activities.
