Respuesta :

Karl will be 15 because half of 16 is 8 and 8+7=15

Answer:

Karl will be 15 y/old

Explanation:

If Gary is twice as old as karl and he's currently 16, the karl must be 8 because 8x2=16

then, seven years go by so Gary's age would be 16+7=23

Karl would be 8+7=15

Hopefully this is the right answer.
