Answer:
The indifference point is 68 shipments.
Explanation:
First, we need to establish the total cost formula:
Local carrier:
Total cost= 4,500 + 250*x
Leasing:
Total cost= 20,000 + 20*x
x= number of shipments
Now, we equal both formulas and isolate x:
4,500 + 250x = 20,000 + 20x
230x = 15,500
x= 67.39 = 68
The indifference point is 68 shipments.
