Final answer:
The optimum order size is 6000 units.
Step-by-step explanation:
To determine the optimum order size, we need to consider the total cost and the quantity of units. The formula for total cost is (ordering cost + inventory cost), and the formula for quantity of units is (total sales / price per unit).
In this case, the ordering cost is given as $25 per order, and the inventory cost is $0.70 per unit. The total sales are $60,000, and the price per unit is $10.
Using the formulas, we can calculate the optimum order size:
- Calculate the quantity of units: 60000 / 10 = 6000 units
- Calculate the ordering cost: 25
- Calculate the inventory cost: 0.7
- Calculate the total cost: (25 + 0.7) * 6000 = 15300
Therefore, the optimum order size is 6000 units.
