I answered this one here.

Melody didn’t agree with my answer (I would have replied but I hadn't noticed her post). I still think my answer is correct and my comptometer was functioning within normal parameters –unlike the Blarney Banker who doesn’t know how to use his comptometer –even when it’s not in for repair.   

 

This question didn’t seem that difficult, but I elaborate more on my reasoning in this post.  

 

Rephrasing the question: In which scenario does the minimum payment drop below the minimum requirement of $94 week?

 

(Original debt) - (current debt) = (amount paid). (Amount paid)  / (number of weeks of payments) = (average amount paid per week).

 

A) 850 - 125 = 725 :  725/7 = 103.57 per week

B) 850 - 175 = 675 :  675/6 = 112.50 per week

C) 850 - 225= 575 :   575/7 =  89.29 per week

D) 850 - 75 = 775 :    775/7 =  96.88 per week

 

Only scenario C) has a per week payment below the $94 minimum.  The answer is C.
