Answer:
The total interest paid by Nell in 20 years is $3,724.80
C is correct
Explanation:
Nell took out a subsidized student loan of $6000 at a 4.8% APR, compounded monthly.
First we find total amount in 10 months
![A=6000(1+(0.048)/(12))^(10)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/24jmrduz7cans8vudca2r9atnqflxi8npy.png)
![A=6244.37](https://img.qammunity.org/2020/formulas/mathematics/middle-school/cl3y7vm8k40p46ba8natntf859j6bsshuo.png)
Now, He has to pay loan off on 6244.37 for 20 years at 4.8% APR
Loan Formula:
![P=(PV\cdot r)/(1-(1+r)^(-n))](https://img.qammunity.org/2020/formulas/mathematics/middle-school/lw4qiit492fqjgjz5f7vtard1tom49wdhr.png)
PV=6244.37
r=0.048/12
n=240
![P=(6244.37* (0.048)/(12))/(1-(1+(0.048)/(12))^(-240))](https://img.qammunity.org/2020/formulas/mathematics/middle-school/p66fc4a6v8o3ts8qk4qm4ciag4noa32rp0.png)
![P=40.52](https://img.qammunity.org/2020/formulas/mathematics/middle-school/mmpvp5dcucfmm4z74d2vuiy028f1nv8t38.png)
Total pay in 20 years = 40.52 x 20 = 9724.80
Total amount took loan = $6000
Interest = 9724.80 - 6000
= $3,724.80
Hence, The total interest paid by Nell in 20 years is $3,724.80
