A particular raw material is available to a company at three different prices, depending on the size of the order:

Less than $100$ pounds $$25$ per pound

$100$ pounds to $3,999$ pounds $$24$ per pound

$4,000$ pounds or more $$23$ per pound

The cost to place an order is $$30.$ Annual demand is $2,600$ units. The holding $($or carrying$)$ cost is $30$ percent of the material price.

What is the economic order quantity to buy each time, and its total cost? $($Round your answers to the nearest whole number.$)$
