Since Bob can't eat too much he can't do no more than 4

C\text{ =}\frac{9!}{4!5!}=126

Bob has 126 possibilities of making his choice.

Since you’re trying to figure out the number of days it takes the kitten to triple it’s weigh you multiply it’s initial weight by 3 (100•3)

Then, you output 300 into the equation and solve
