Answer:
$6,427.99
Step-by-step explanation:
-We first find the effective annual interest rate as follows:

#We the use this rate to find the compounded amount after 18 years:

Hence, the amount after 18 years is $6,427.99
Standard form is ax+by=c
mnus 7y both sides
6x-7y=0
24000 + 3000x = 30000 + 2400x
3000x - 2400x = 30,000 - 24,000
600x = 6000
x = 6000/600
x = 10 years
Here is how to solve it with long division and synthetic division.
