Aerotron Electronics has just bought a used delivery truck for $15,000. The small business paid $1,000 down and financed the rest, with the agreement to pay nothing for the entire first year and then to pay $ 506.83 at the end of each month over years 2, 3, and 4 (first payment is in thirteenth month). a. What nominal interest rate is Aerotron paying on the loan? %
b. What effective interest rate are they paying? %
c. How much of the fourteenth month's payment is interest? How much is principal? payment interest = $ , and principal = $
d. How much of the eighteenth month's payment is interest? How much is principal? payment interest = $ , and principal = $
e. How much of the twenty-second month's payment is interest? How much is principal? payment interest = $ , and principal= $

a) 12.23%

b)  12.94%

c) 14th month payment interest = $157.33

   14th month principal =  $369.50

d)  18th month payment interest = $142.04

    18th month payment interest = $384.79

e) 22nd month payment interest = $126.12

   22nd month payment interest = $400.71

Explanation:

price of truck = $15000

down payment = $1000

Loan amount = $14,000

assume monthly interest rate = r%

Loan amount after 1 year will be = 14000 * (1+r%)12

next we will determine the annuity factor = [  (1/r)-[(1/r)*(1/ (1+r)t)] ]

r = periodic interest rate , t = number of payments

monthly loan payment = $14000*(1+r%)12 / [  (1/r)-[(1/r)*(1/ (1+r)36)] ]

hence r = 1.019%

a) nominal interest rate

=  1.019% *12 = 12.23%

b) effective interest rate

= (1+1.019%)^12 -1 = 12.94%

c) 14th month payment interest = $157.33

    14th month principal =  $369.50

d) 18th month payment interest = $142.04

    18th month payment interest = $384.79

e) 22nd month payment interest = $126.12

   22nd month payment interest = $400.71

answer; ///(c) i believe its it ignores cash flows following the payback period;

net worth is the difference between what you own and what you have. if you exceed your liabilities you have a positive net worth. if your liabilities are greater than your assets you have a negative net worth. its a snapshot of your financial situation. if you calculate your net worth you will see the end result of everything you've earned and spent as of now. net worth statements and all you asked of can you determine where you are, how to get where you want to be, if your spending   to much. honestly it can tell you a lot of things. i can go on, but you can paint the picture from here.
