Answer:

Transworld Deliveries

1. Transworld Deliveries should purchase additional vehicles and hire additional drivers.

2. I recommend 14 new vehicles with drivers to bring the number from 35 vehicles to 49 vehicles.

Step-by-step explanation:

a) Data and Calculations:

Vehicles requirements (Range) 35 and 80

Own Vehicles being moved = 35

Cost of own fleet = $730 per vehicle

Cost of leasing = $1,300 per vehicle

Decision: Purchase additional vehicles or

Lease additional vehicles

Expected Vehicles Required:

Requirements 20 35 50 80

Probability 0.35 0.15 0.1 0.4

Expected value 7 5 5 32

Total expected number of vehicles required = 49

Additional vehicles required = 49 - 35 = 14

Cost of leasing additional vehicle = 14 * $1,300 = $18,200

Cost of purchasing vehicles and hiring additional drivers = $730 * 14 = $10,220

Difference in costs = $18,200 - $10,220 = $7,980
