1a. Suppose the supply curves for pineapples in East Utopia and West Utopia are given as follows:

-------------------------------------------------

Supply (East Utopia): P = 29 + 0.4Q_E

Supply (West Utopia): P = 2 + 1.1Q_W

-------------------------------------------------

If the price of pineapples in Utopia is 20.4 Utopian dollars per kg, the total quantity supplied from Utopia as a whole is [Answer] kgs.

(In decimal numbers, with two decimal places, please.)

1b. Continue with the last question.If the total quantity supplied from Utopia is 329 kgs, the marginal cost of production the 329-th kg is [Answer] Utopian dollars per kg.

2a.There are two groups of consumers, A and B, with the following demand relations, respectively:

---------------------------------

Demand A: P = 160 Q_A

Demand B: P = 80 - Q_B

---------------------------------

The market supply is

P = 0.33Q

Given this information, we can compute that the market equilibrium price is [Answer].

(In decimal numbers, with two decimal places, please.)

2b. Continue with the last question. The total consumer surplus at the equilibrium is [Answer].

(In decimal numbers, with two decimal places, please.)
