Explanation:
let's say AD is the amount of money for Darcy, and AG is the amount of money for Gina.
AD = 1000×(1.02)^t
AG = 5000×(1.02)^t = 5×AD
because the term (1.02)^t is the same for both, the original ratio of 1000/5000 remains the defining factor for the relative comparison.
so, no matter how large t gets, AG will always be 5 times greater than AD .
therefore, D is the right answer.
