Nehemiah · Answer 1

Since you know Rolando's age is going to be 3/2 of his sister's age in 5 years. So you would add 13+5 and you would get 18.

Then you would divide 18 and the numerator 3 which would get you 6.

Then you multiply 2 and 6 and you get 12. But your not done yet because you need to know how old Marisa would be in 3 years. So then, you subtract 12 and 5 which gets 7. This is her age right now. Now add 7 and 3 and you get 10.

Answer: 10 years old
