How many pets does Ed have? ** If Ed has 2 dogs and 3 cats he has in total 2+3 = <<2+3=5>>5 pets that are not fish
How many fish does Ed have? ** If Ed has twice as many cats and dogs combined he has 2*5 = <<2*5=10>>10 fish
How many pets does Ed have in total? ** Therefore, in total Ed has 5+10 = <<5+10=15>>15 pets
