A day-trader plans to invest a total of $23,100 into 15 separate investments. If each investment requires a minimum deposit of $1,400, then which of the following is the maximum amount that she could put into any one investment? Select
A) $2,800	B) $3,000	C) $3,500	D) $3,800	E) $3,900
We can also just keep track of the HUNDREDS DIGITS(since the hundreds digit is different for each answer choice).   Total of 14 minimized investments = (14)(1400) = $???600   The 15th investment + $???600 = $23,100   So, the HUNDREDS DIGITS of the 15th investment must be 5   Answer: $3,500
