Tourists who travel to London often stop to see the Tower of London.

Many of these tourists then get lunch at a restaurant near the Tower. In this area there are both high and low quality

restaurants. If they could be sure that the restaurant was high quality, each tourist would be

willing to pay 20 for lunch. If they could be sure that the restaurant was low quality, each

tourist would be willing to pay 10 for lunch.

Suppose that the supply of lunches available in the area is:

High quality lunches supplied: P = 5 + 0.04Q

Low quality lunches supplied: P = 5 + 0.01Q

If tourists are uninformed and cannot tell the quality of a lunch before buying it, what are

the final quantities and single price that this market will settle to?
