Ed has 2 dogs, 3 cats and twice as many fish as cats and dogs combined. How many pets does Ed have in total?
Let’s work this out in a step by step way to be sure we have the right answer.
15
If Ed has 2 dogs and 3 cats he has in total 2 + 3 = 5 pets that are not fish.

If Ed has twice as many cats and dogs combined he has 2 * 5 = 10 fish.

Therefore, in total Ed has 5 + 10 = 15 pets.

The final answer: 15
