Hula Products has reintroduced the hula hoop to the world and faces a growing demand for its product in two distinct markets: the United States and Europe. Demand in these markets is:

PU = 20 - .1QU

PE = 10 - .05QE

where all quantities are expressed in thousands of units (i.e. QU = 50 means 50 thousand units). The company has an existing stock of 95 thousand hula hoops.

How many should be sent to Europe?
