To determine the Annual Percentage Rate (APR), we need to understand that in this context, the APR is equal to the yearly interest rate offered by Sam Seller.
Given:
- The yearly interest rate = 19%
Now, since the APR in this context is the same as the yearly interest rate, to the nearest tenth, the APR is:
[tex]\[ \boxed{19} \% \][/tex]
This means that when Sam Seller offers credit at an interest rate of 19% per year, the Annual Percentage Rate (APR) is exactly 19%. Thus, the APR rounded to the nearest tenth is 19.0%.
