In Figure 32.1, at the market equilibrium price-quantity combination, the value to consumers is 

The balance of trade is derived by subtracting merchandise imports from merchandise exports

Indicate whether the statement is true or false

Use the following general linear supply function:Qs = 40 + 6P - 8PI + 10F   where Qs is the quantity supplied of the good, P is the price of the good, PI is the price of an input, and F is the number of firms producing the good. If  PI = $20, F = 60, and the demand function is Qd = 600 - 6p the equilibrium price and quantity are, respectively,

A. P = $8 and Q = 326. B. P = $10 and Q = 540. C. P = $8 and Q = 640. D. P = $10 and Q = 640. E. none of the above.
