Carmen had 28 cats and 18 dogs before she gave 3 of the cats up for adoption. How many more cats than dogs does Carmen have now?
First find the number of cats Carmen has left: 28 cats - 3 cats = <<28-3=25>>25 cats
Then subtract the number of dogs from the number of cats to find the difference: 25 cats - 18 dogs = <<25-18=7>>7 more cats
