Maximum weekly profit in manufacturing and selling desk furniture

August 22, 2010 - 5:39pm

A company that builds and sells desks is operating under perfect competition and can sell at price of 400 dollars per desk all the desks it produces. If x desks are produced and sold each week and C(x) dollars is the total cost of the week's production, the C(x)= 2x^2 + 80 + 6000. Determine how many desks should built each week for the manufacturer to have the greatest weekly total profit. What is the greatest weekly total profit

Application of Differential Calculus.... Need some help...

August 19, 2010 - 10:46pm

patulong po... thanks..

A car manufacturer buys 6000tires a year from a distributor. The Ordering Fee is P8,000.00 per shipment, the Storage Cost is P384.00 per tire per year and each tire cost P100.00. Suppose that the tires are ...used at a constant rate throughout the year and that each shipment arrives just as the p...receding shipment has been used up. How many tires should the manufacturer order each time to minimize the cost.

Thanks...
