Answer:

Step-by-step explanation:
<h2>This account can be modeled using the compound interest formula.</h2><h2>the compound interest formula is expressed as</h2>

Where
A =final amount = y
P=initial principal balance
= $300
r=interest rate = 16%= 0.16
t=number of time periods elapsed= x
Hence the equation to model his account balance/ final amount A (y) after time (x) years is

40 = n-.40n
40 =n(1-.4)
40 = n(.6
divide by .6 on each side
40/.6 =n
n=66 2/3
Six numbers that are not perfect cubes 43, 0, 61, 15, 14, and 3
