Answer:
cost of financing is $12108.62
interest is 5.614 %
Explanation:
given data
payment = $10000
principal = $1350
time t = 10 year = 10 × 4 = 40
rate r = 5.5 % = 5.4 /4 = 1.375 %
to find out
purchase price and cost of financing and rate of interest
solution
we know here purchase price is calculated as
purchase price = payment + present value .................1
present value = principal (1+r) ( 1-
/ r )
put here value
present value = 1350 (1+0.1375) ( 1-
/ 0.01375 )
present value = 41891.3833
so from equation 1
purchase price = 10000 + 41891.3833
purchase price = $51891.38
and
so amount of payment is here
amount of payment = 10000 + 40×1350
amount of payment = $64000
so here cost of financing is here
cost of financing = 64000 - 51891.38
cost of financing = $12108.62
and
so here
1 + interest =

1 + interest =

interest = 0.0561448
interest = 5.614 %
