Explanation:Let x be the price of wheat, y be the price of corn, and z be the price of rye.From the first transaction, we have 5x + 2y + 3z = 20.80.From the second transaction, we have 2x + 3y + 5z = 20.80.From the third transaction, we have 3x + 5y + 2z = 20.80.Solving these equations, we get x = 4, y = 2.08, and z = 2.40.Therefore, the price of corn is $2.08 per bushel.
