Answer 1

To triple, means to multiply that number by 3.
To cube means to times that number by it's self three times.
So, in conclusion, the answer would be Kayla.

Answer 2

Kayla had more money after 2 years.

Explanation:

Zach invested $50 and was able to triple his money in two years.

Triple the amount means three times.

So, after 2 years Zach's amount became ;

`50*3=150` dollars

Kayla also began with $50 in investments, and was able to cube her money in two years.

Cube means the number itself times to itself three times like 50 x 50 x 50

So, Kayla's amount becomes:

`50^(3)=125000` dollars

Hence, Kayla had more money after 2 years.
