Given:
loan amount = 300
finance charge = 20
term = 14 days.
To solve for APR.
1. Divide the finance charge by the loan amount.
20/300 = 0.0667
2. Multiply the result by 365.
0.0667 x 365 = 24.35
3. Divide the result by the term of the loan.
24.35/14 = 1.74 (APR in decimal format)
4. Multiply the result by 100.
1.74 x 100 = 174% APR
