Answer:

70% of the juice boxes are left.

Step-by-step explanation:

10 is the total number of juice boxes which means that 10 is 100%

If there are 10 total juice boxes and Sam drank 3, there are 7 juice boxes left. Sam drank 30% of the juice boxes which means that there is 70% of the juice boxes left.

Hope this helps!
