A store estimates their holding costs at $20\%$ and incurs a fixed cost of $$76\mathrm{.}00$ for each order. Demand for an item is $1\mathrm{.}725$ units per year. A supplier offers a price of $$14\mathrm{.}00$ each for quantities of $425$ or fewer and a price of $$13\mathrm{.}30$ for quantities over $425$ units. Round your answer to the nearest integer value. How many units should the retailer order at one time? What is the total annual cost at this order point?
