The government occasionally uses price support to aid farmers. A price support works like this: the government promises to buy all the produce the farmer cannot sell in the market at some pre-set price. For example, if the price of lettuce was $.30 a head in the market, the government might offer a price support of $.50 a head. Show and explain that the effect of a price support is the same as a price floor. You should use graphs to aid your explanation.
