I followed the formula but keep getting the wrong answer. I got $1876 and that was not correct.

Using a computerized Inventory Management System, a Paint Supply Store franchise continuously monitors the inventory of all the paint located at each of their 15 stores and their distribution warehouse. The Paint Supply Store franchise sells an average of 70 gallons of Purple Paint every week (for 52 weeks per year). Their current policy is that when they place an order for Purple Paint from their supplier, they order 90 gallons at a price of $4.00 per gallon. [The company does not hold Safety Stock] It takes 2.50 weeks to receive an order from the supplier. Administrative costs for Ordering paint have been estimated to be $35 per order. Holding Costs = 40% of the purchase price per gallon per year. What is the Total Annual Inventory Cost for the company's current policy?
