Are You a Money Maker?

Logic Level pending

This is an interesting problem that I found in a Cambridge Thinking Skills past paper:

The table below shows the exchange rate for the Bol (B) and Uno (U) against the Dollar ($) from January to December.

$1000 is invested in the currency market over this one year period, exchanging between the three currencies. Money can be changed into Bols or Unos in January, March, June, September and December. Ignoring commission, what is the maximum amount of Dollars that could have been generated by December?

I'm really interested in hearing your money-making strategies. What is the most efficient algorithm when tackling a problem of this nature?
