Based on the information from the image:

Mr. Ko buys water bottles in packs of 8. The table shows the number of bottles he will have for 1, 2, 3, and 4 packs.

To calculate the number of water bottles for 4 packs: $\text{Number of bottles} = 8 \times 4 = 32$

Thus, if Mr. Ko buys 4 packs, he will get 32 water bottles.

1. How many packs would Mr. Ko need if he wants exactly 40 bottles?
2. What is the total number of bottles for 6 packs?
3. If each pack costs $5, how much would 4 packs cost?
4. How many bottles are left if Mr. Ko buys 4 packs and gives away 10 bottles?
5. What fraction of a pack corresponds to 20 bottles?
