Answer: three times as large
Explanation:
Economic order quantity will be calculated as follows:
EOQ = ✓(2DS/H)
D = Demand in units
Here S = Ordering cost = $10
H = Holding cost
Since S = $10
Therefore, EOQ will be:
= ✓(2DS/H)
= ✓(2 × 10 × D/ H)
= ✓(20D/H)
Since we're to increase the order cost from $10 per order to $90 per order, then EOQ will be:
Since S = $90
Therefore, EOQ will be:
= ✓(2DS/H)
= ✓(2 × 90 × D/ H)
= ✓(180D/H)
3✓20DH
The revised EOQ will then be 3 times as large.
