Answer: 393.73%.
Explanation:
To calculate the APR, we need to consider the finance charge and transaction fee over the loan term. The total cost of the loan is $21.00 (finance charge) + $16.00 (transaction fee) = $37.00.
Now, let's calculate the APR using the formula: APR = (Total cost / Loan amount) * (365 / Loan term in days) * 100.
APR = ($37.00 / $245.00) * (365 / 14) * 100 ≈ 393.73%
Therefore, the APR of Uriel's loan is approximately 393.73%.
