Help me with the D.R. Money......................

Try using this converter

So, if RD $30 is run in your converter, it comes up with about 63 U.S. Cents, which I am having a hard time believing you could get a cab ride for.

I could still use some help here.

That is correct.  However I think recently there was a price increase in the cost of a Gua-gua and public (shared public taxi) to maybe 40 pesos or 40RD and this would be about 85 cents US.
Some things are very cheap here.  Bottled water for instance. A 5 gal blue bottle of water here runs about 75 cents.
Other things very expensive. A gallon of gas (regular) is now nearly $4.50US a gallon

Your calculation is correct. Some things are cheap.

Easy and who to do in your head is 50 to 1. So 50 rd is about a dollar US. 

50= 1
100 =2
150 = 3
200 = 4
250 = 5
