For example, suppose you have containers of size 20, 15, 10, 5, and 5 liters. If you need to

For example, suppose you have containers of size 20, 15, 10, 5, and 5
liters. If you need to store 25 liters, there are four ways to do it:
• 15 and 10
• 20 and 5 (the first 5)
• 20 and 5 (the second 5)
• 15, 5, and 5
Filling all containers entirely, how many different combinations of containers can exactly fit
all 150 liters of eggnog?
Filling all containers entirely, how many different combinations of

Find the minimum number of containers that can exactly fit all 150 liters of eggnog. How many
different ways can you fill that number of containers and still hold exactly 150 litres?
Find the minimum number of containers that can exactly fit all 150 liters of
eggnog. How many different ways can you fill that number of containers and
still hold exactly 150 litres?
In the example above, the minimum number of containers was two. There were three ways to use
that many containers, and so the answer there would be 3.
