Answer:
Option C is correct.
Explanation:
Felipe transferred a balance of $3700 to a new credit.
The card had an introductory offer of 5.9% APR for the first 4 months and after that 17.2 % APR.
The card compounds interest monthly, that gives n = 12
So, the equation that represents Felipe's balance at the end of the year will be:
![p(1+(r)/(n))^(a)* (1+(r)/(n))^(b)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/a9ilft6xniqz7eyh9jayo7qvbm0a29jh3p.png)
Here a is the introductory rate number of months that is 4
And b is the rest of the standard months that is 8
So, the expression becomes:
![3700(1+(0.059)/(12))^(4)* (1+(0.172)/(12))^(8)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/x4wxuykru6j006b3cga9rmyv9p1eum0myw.png)
