Assume it costs Microsoft $4,300 to manufacture 5 Xbox 360s and $6,850 to manufacture 10. Obtain the corresponding linear cost function. C(x) =        What was the cost (in dollars) to manufacture each additional Xbox? $  Use the cost function to estimate the cost of manufacturing 50 Xboxes (in dollars). $

It costs $1000 to produce 100 t-shirts in a day, and it costs $1300 to produce 140 t-shirts in a day. Assume that the daily cost is a linear function of the number of t-shirts produced per day.a. Determine the marginal cost per t-shirt.b. Determine the fixed daily cost.

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 $
