It is known of the market of sandwiches that for 700 forints consumers don't buy any (but for lower price they were able to sell some). At the same time, marketing experts state that a 1 forint decrease in the price increases
the demand for sandwiches by 4 pieces. Please, use decimal POINT and 2 decimals if needed. Use CAPITAL Q
in the function (it is market quantity).
The inverse demand function is P=
How much is the demanded quantity if the market price is 200?
How much is the consumer surplus at the given price?
