Answer: Pn= 10500(1+ 0.07(11-n))
Step-by-step explanation:
From the question it is given that
Pn= 10500 + 7% of Dn eqn 1
Where Pn is payment at year n
And Dn is outstanding debt at year n
n= 1,2,3...,10
D1= 105000
D2=105000-10500
Dn=105000-10500(n-1) eqn2
Therefore, substituting eqn2 into eqn1
Pn= 10500+7% of (105000-10500(n-1))
Pn= 10500+ 0.07(105000 - 10500(n-1))
Pn= 10500(1+ 0.07(10 - (n-1)))
Pn= 10500(1+ 0.07(11-n))
30 degrees.
Because a right triangle has a 90 degree angle; and a total of 180 degrees.
Therefore:
180-90-2x-x=0
Solve for X:
90-3x=0
3X=90
X=30.
