Annual demand for an item is 35,000 units. The holding cost rate is 15% of the item cost. Ordering costs are $10 per order. Quantity discounts are available according to the schedule below:

Quantity Price per Unit ($)

1-99 50.00

100-299 49.50

300-399 49.25

400+ 49.00

Question 30) What is the optimal order quantity? If necessary, round to the nearest whole number.

Question 31) From the previous problem, what is the total annual cost of your policy

Question 32) Assume 52 5-day weeks per year. If the lead-time is 3 days, what should the reorder point be? If necessary, round your final answer UP to the nearest whole number.

112,113,113,=114

B)8,321,250

C)403.85

Explanation:for 1-99 quantity

EOQ=√2tD/C

√(2×10×35000/0.15×50

=111.55

For 100-299

EOQ=√35000×20/0.15×49.5=112.68

300-399

EOQ=√35000×20/0.15×4=113.25

When q>400

EOQ=√700,000/7.35=113.83

B)(60+59.50+59.25+59)×35000=$8,321,250

Average usage 134.61=35000/52. /5

Reorder level = avg usage×lead time

134.61×3=403.84

you get one warning and if you do something to violate the guidelines of after that you get kicked off.
