A day-trader plans to invest a total of $23,300 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?
Choose the correct choice from the following answers:
A) $2,800
B) $3,000
C) $3,700
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 = $23,300   So, the HUNDREDS DIGITS of the 15th investment must be 7   Answer: $3,700
