Suppose the current market price of corn is $3.75 per bushel. your firm has a technology that can convert 1 bushel of corn to 3 gallons of ethanol. if the cost of conversion is $1.60 per bushel, at what market price of ethanol does conversion become attractive?

At 1.783 or more, the conversion yield better gain than sales the corn

Explanation:

The ethanol conversion become attractive if the cost for doing the conversion are lower than the sale revenue for the product.

total cost: raw materials + conversion cost

corn price:           $  3.75

conversion cost:  $  1.60

Total cost:            $  5.35

output: gallon of ethanol per bushel

3 gallons of ethanol per bushel

total cost / output = 5.35/3 = 1.783 cost per gallon
