Question

Kevin has a rabbit, a ferret, a gerbil and a turtle he feeds them in a different order each day. In how many different orders can Kevin feed his pets?

Answer 1

1. Rabbit, ferret, gerbil, turtle
2. Rabbit, gerbil, turtle, ferret
3. Rabbit, turtle, ferret, gerbil
4. Rabbit, ferret, turtle, gerbil
5. Rabbit, gerbil, ferret, turtle
6. Rabbit, turtle, gerbil, ferret

Those 6 combinations times 4 animals mean that there should be 24 different orders Kevin can feed his pets.

Answer 2

Or easier way: 4 animals • # of days. BTW, wouldn't the answer be 28 days, because there are 7 days in a week.
