Answer: At least 24 months, with a final payment of 50 dollars on the 24th month.
Explanation:
5,800/250 = 23.2
An easier way to do this is get this answer, and then multiply 250 by 23 which gives you ($)5,750, then just subtract that from $5,800 leaving you with 50, which is your last payment which is where the .2 comes from. Meaning it will take 24 months at the least, giving you $50 as your final payment.
