A loan has a variable interest rate that fluctuates between 6% and 8% of the base payment per month. If base payments remain at $400 each month and an additional monthly surcharge of 2% is added to the combined (base + interest), what would be the greatest possible payment due in any given month?
Pick:
A) $435.32	B) $436.48	C) $438.16	D) $440.64	E) $442.32
The maximum interest in one month is 8%*$400=$32.   The combined payment (base plus interest) is $400 + $32 = $432.   The greatest possible payment is: 1.02*$432  400 +  32=
