A loan has a variable interest rate that fluctuates between 5% and 10% of the base payment per month. If base payments remain at $200 each month and an additional monthly surcharge of 1% is added to the combined (base + interest), what would be the greatest possible payment due in any given month?  Pick one:
A) $220.00
B) $222.20
C) $224.20
D) $224.40
E) $225.60
The maximum interest in one month is 10%*$200=$20.   The combined payment (base plus interest) is $200 + $20 = $220.   The greatest possible payment is: 1.01*$220  200 +  20=
