The 19% APR is the annual interest rate, but it is compounded monthly. What is the
monthly interest rate?

Other loan info (I don't know what all you need to calculate this)

The debt owed is 910$ and the minimum payments is 2.5% or ten dollars whatever is larger. Assume Zach is going to pay only the minimum. If he only pays minimum it would take him 154 months.
