a. Determine which delivery alternative would be most economical for 95 boxes of parts. Each box costs $300 and annual holding cost is 20 percent of cost. Assume 365 days per year. Freight costs are: Alternative Freight cost (for all 95 boxes) Overnight $325 Two-day 295 Six-day 235

What's the alternative

1.Overnight

2. Two- day

3. Six day

b. For what range of unit cost for a box would each delivery alternative be least costly? (Do not round intermediate calculations. Round the final answers to 2 decimal places.) Overnight is cheapest if unit cost > $

Two-day delivery is cheapest if $ $ unit cost < $

Six-day delivery is cheapest if unit cost < $
