Kind of a trick question because if all she pays is $2,150 which is the $2,000 plus the $150 fee then technically an APR didn't apply. By hiding the APR in a fee they get unsuspecting customer's to sign up for these. From an APR perspective based on one Bi-weekly payment, it would take an APR of 555.5715% to generate a $150.00 in interest in 2 weeks.
