A firm produces headphones in two qualities, Basic (B) and Premium (P). For the coming year, the estimated quantity produced of B is 60% higher than that of P. The firm makes a markup of 170% on both products. The ratio between the profits per unit between P and B is 2. The cost price for P is $260. If the profit target is $115 362 over the next year, how much of each of the two qualities must be produced and what are the two selling prices? (Round the quantities to the nearest unit and the prices to 2 digits after the decimal point if needed) Quantity of B = Answer units Quantity of P = Answer units Selling price of B = Answer $ Selling price of P = Answer $

Let’s assume that in Kansas, a family farmer sells wheat in a perfectly competitive market. After increasing the production of wheat from 220 bushels to 240 bushels, the total revenue of the farmer increases from $6,600 to $6,700. What was the marginal revenue of this increase in production in dollar?
