What is the rest of the question??
Do number 11 in your own way.

Not sure if its right but did my best!!
If I understand your question correctly, you want to know how many pounds of vegetables the zoo feeds the animals a month if its a 30 day month?
In that case it would be 23 pounds times 30 days which is 690 pounds of vegetables. SO the zoo feeds the animals 690 pounds of vegetables to the animals each month.
Is that what your asking for?
