Answer:
Semiannual payment = $ 1391.37
Total payment = $ 8348.22
Interest paid = $ 848.22
Step-by-step explanation:
Since, the semiannual payment formula of a loan,
Where,
PV = present value of the loan,
n = number of semiannual payments,
r = annual rate,
Here, PV = 7500, r = 6.3% =0.063, n = 6,
By substituting the value,
The semiannual payment would be,
Also, total payment = semiannual payment × total semiannual periods
= 1391.37 × 6
= $ 8348.22,
Also, the interest paid = total payment - present value
= 8348.22 - 7500
= $ 848.22
Answer:
Step-by-step explanation:
Let's substitute the first equation into the second one.
- Multiply by
and bring all the terms to one side.
I'll use my graphical calculator to solve this but you could factor:
(All rounded to 2 decimal places)
Now we can substitute these values into an equation for
