In a given year, firm A produces 50,000 bushels of wheat, sells 20,000 bushels of wheat to firm B at $3 per bushel, exports 25,000 bushels of wheat at $3 per bushel, and stores the rest as inventory. Firm A pays $50,000 in wages to consumers. Firm B produces 50,000 loaves of bread and sells all of it to domestic consumers at $2 per loaf. Firm B pays consumers $20,000 in wages. The economy also imports and consumes 15,000 loaves of bread for $1 per loaf. (a) Calculate Net Exports. (b) Find Investment. (c) Calculate GDP.
