Answer:
$919.98
Step-by-step explanation:
To solve using a financial calculator do
N=8
I/Y=10
PMT=85
FV=1000
CMPT PV get 919.98
To do by hand find the present value of the interst payments
85*(1-(1/1.1)^8)
which is 453.4687
Find the present value of the final ballon payment
1000*(1/1.1)^8
which is 466.507
take the sum
466.507+453.4678= 919.98
3 -12i
(-6-8i)-(-9+4i)
distribute the minus sign
-6 -8i +9 -4i
combine like terms
-6+9 -8i -4i
10 i guess
cause
8*3=24
3*10=30
