Question 1033294
Assume you have a balance of $3200 that you want to pay off. The cred card APR is 21% and you want to pay it off the balance in 2 years. 
-----
Mortgage payment formuls:: c = [r*P]/[1-(1+r)^-N]
-------
Your problem:
c = [(0.21/12)*3200]/[1 -  (1.021)^(-24)
----
= 56/0.3927
-----
= $142.60 per month for 24 months
