The total cost for Astro to make direct, single-order shipments to all of its customers is $40000 per week. (Enter your response as a whole number.) The average truck utilization level for the single-order shipment option is 0.8%. (Enter your response rounded to one decimal place.) b.

Local deliveries to each customer would tack on another $50 per customer per week. The total cost of the break-bulk warehousing option is $16,600 per week. (Enter your response as a whole number.) By going with a break-bulk solution, Astro could save $23400 per week. (Enter your response as a whole number.) c. The warehousing cost would need to be greater than or equal to $ per hundred-weight for the break-bulk option to be no more attractive than direct shipments.
