Answer:
$197.46 less each montly payment if you pay it in 5 years than 3 years
Step-by-step explanation:
From 20000 you pay 10% , 10% of 20,000 is:
20,000 * 10/100=20,000*0.01=2,000
so you finance 20,000-2,000=18,000
monthly payments are calculated as:
[tex]A=P\frac{r(1+r)^n}{(1+r)^n-1}[/tex]
where r is the montly rate as decimal ( anual rate/12) and n is the total number of payments , for 5 years= 12*5 and for 3 years =3*12 and P =18,000
for 3 years the monthly payments are:
[tex]A=18,000\frac{0.01(1+0.01)^36}{(1+0.01)^36-1}=400.40[/tex]
for 5 years
[tex]A=18,000\frac{0.01(1+0.01)^60}{(1+0.01)^60-1}=597.46[/tex]
the difference 597.46-400.40 = 197.46 is your answer.
