Answer:
n = -3
Step-by-step explanation:
The question is asking you to solve for your variable N. To do so, you must use difference operation(s) and their respective principle of equality to isolate the variable.
To get n by itself on one side of the variable, the term -7n by -7. What you do to one side of the equal sign, you must also do to the other due to the division principle of equality. Thus, you also divide 21 by -7.
Once you simplify, you are left with -3 = n or n = -3, which is your answer.
Step-by-step explanation:
i = interest 3% for 30 years
This is a simple dynamical system for whom the the solutions are given as
putting values we get
S=2000[\frac{(1.03)^{30}-1}{0.03}](1.03)
= $98005.35
withdrawal of money takes place from one year after last payment
To determine the result we use the present value formula of an annuity date
we need to calculate R so putting the values and solving for R we get
R= $6542.2356
