there are 300 animals in the zoo there are 20 enclosures that hold 4 animals each 25 enclosures that hold 3 animals each and 42 enclosures that hold 2 animals each the rest of the animals all have their own enclosures how many have their own enclosure

* = multiplied by
(20*4) + (25*3) + (42*2) = number of animals in other enclosures. The difference between that and 300 is your answer.
I hope this helps. Thanks for asking.
