Answer:
Cady will have to leave the money in the bank for 5 years.
Step-by-step explanation:
Given that Cady has invested $ 3000 in an account with an interest rate of 4%, to know how much time must be invested to obtain $ 600 in interest, the following calculation must be performed:
3000 x 1.04 = 3.120
Thus, each year the investment will yield interest for $ 120. Therefore, since 600/120 is equal to 5, Cady will have to leave the money in the bank for 5 years.
