the first one the ball is 5$ because 100+5=105 so 105+5=110
the second one is still five days.
the 3rd one i just put in a random number that could fit the rabbit seeing as how it is smaller than the cat. at the end the cat weights 7 the dog 17 and the rabbit 3.
i could see the answer for the the last one so i gave on it. sorry
