Usually the best place to start is at your local bike shop.  Tell them what
you have just told us.  I would imagine that they would suggest some sort of
hybrid.  A hybrid is kind of like a mountain bike with skinny tires (but
not as small as a road bike), lower quality components (you don't need the
expensive stuff for streets and gravel roads), and a relaxed riding position
with high handle bars and a plush seat.  As far as price range, I can't give
you any specific examples of bikes you might purchase because I don't know
what shops you have in your area.  What ever you decide on, you do get what
you pay for.  More money is equivalent to better components (easier to shift,
less maintenance, longer lasting) and a better quality frame (rust resistant,
light weight).
A few things to keep in mind:
        It is worth buying a bike locally.  Most dealers will service the
bikes they sell free of charge for the first year or so, and at a discount
after that.
        Look for a shop that is knowledgeable and friendly.  Many shops
have part time help that is less than well informed.  Ask the salesman
what he/she rides.  If they don't bike, go somewhere else!
        Don't pay the sticker price!!!  You wouldn't pay the sticker price
on a car, don't pay it on a bike either.  Look for a buyers guide, most
bike mags come out with one once a year, at the library.  Find out the "list
price" of a bike you are considering.  Subtract 15 to 25 percent and that
is what you should expect to pay.  If you can't get a good price go to 
nother
shop.
Have fun riding your new bike!
