You want the answer or do you want me to walk you through it?

OpenStudy (anonymous):

walk though it cause I don't get none of those problems

ok so claudia is 5 years older than nikki and nikki's twin brother hunter is 12 so hunter is 12 nikki is 12 and claudia is 17

OpenStudy (anonymous):

the dog is a decade younger than nikki (a decade is 10 years) so the dog is 2

OpenStudy (anonymous):

and the dog is 3 years younger than philip and since we know the dog is 2 then we know philip is 5

OpenStudy (anonymous):

and since philip is only one year older that sara that means she is 4 and thats the answer :)
