Scrat [10]

Martin deposits $200 in a savings account that earns 5% annual interest.

year interest balance

1 200 * 5% 200(1.05)

2 200(1.05) * 5% 200(1.05)^2

3 200(1.05)^2*5% 200(1.05)^3

y 200(1.05)^y

=> m = 200 (1.05)^y

four years later, cary deposits $200 in an account earning the same interest.


year interest balance

5 200 * 5% 200(1.05)

6 200(1.05) * 5% 200(1.05)^2

7 200(1.05)^2*5% 200(1.05)^3

y 200(1.05)^(y-4)

=> c = 200(1.05)^ (y-4)

Answer:
Martin: 200(1.05)^y
Cary: 200(1.05)^(y–4)
