5 . The supply of wheat is given by the following equation: ew =-6+4Py -2Pc -PF where LW is the quantity of wheat supplied, in millions of bushels; Pw is the price of wheat per bushel; Ic is the price of corn per bushel; and PF is the price of tractor fuel per gallon. Graph the inverse supply curve when corn sells for $4 a bushel and fuel sells for $2 a gallon. What is the supply choke price? How much wheat will be supplied at a price of $4? $8? What will happen to the supply of wheat if the price of corn increases to $6 per bushel? Explain intuitively; then graph the new inverse supply carefully and indicate the new choke price. d. Suppose instead that the price of corn remains $4, but the price of fuel decreases to $1. What will happen to the supply of wheat as a result? Explain intuitively, then graph the new inverse supply. Be sure to indicate the new choke price
