Answer:
4 gallons
Explanation:
If a container is 3.50 then we can divide 15 by 3.50. This will get us 4.3. Since this is not a whole number, we round down, thus getting 4. Now to check our answer we multiply 3.50 by 4, getting 14. Since 14 is less than 15, we know we can buy 4 containers of orange juice. So c=4.
